Best use cases
A minimalist style single-line art avatar design prompt, including detailed subject extraction logic, artistic line standards, dark emotional backgrounds, and sparse improvised colored embellishments. It is highly suitable for scenarios requiring rapid drafting like XiaoHongShu covers, avatars, and personal homepage visuals. The core value is not just stacking style words, but solving the pain point of 'having a portrait subject but lacking a premium cover composition' by locking down the subject and composition first, then swapping variable information.
Visual style
The stylistic tone of "GPT2 Minimalist Line Art Avatar Optimizer" is minimalist, sketch, and line art. When interpreting the image, focus on character posture, framing, and minimalist style, followed by the relationship between the portrait, character, and background; negative space, hierarchy, and colors exist purely to serve this primary relationship.
How to generate a new image
1Copy the entire "GPT2 Minimalist Line Art Avatar Optimizer" prompt, keeping the style, subject, composition, material, lighting, and aspect ratio descriptions.
2Modify only the theme or subject first, keeping the style, material, and lighting descriptions intact.
3Generate 2-4 images using default parameters in GPT-image-2 or your preferred tool, with an aspect ratio like 16:9 for reference.
4Check against the target avatar visual: Is the subject clear? Is the information hierarchy legible? Are colors and style close to the reference?
5If it drifts, reduce background noise first, then reinforce core style words or adjust the ratio, avoiding changing too many variables at once.

Full remixed prompt
Please convert the input image into a minimalist single-line illustration suitable for a social media avatar, with a default aspect ratio of 1:1. The subject can be a person, cat, dog, other animals, or plants. Based on the input subject type, automatically extract the most recognizable outer contours and key features, and summarize them into an artistic, minimalist single-line avatar / portrait illustration. The overall goal is not mechanical tracing, but retaining the subject's spirit and recognition, reconstructing it with single lines in a more premium and soulful manner. [Subject Processing Logic] If the subject is a person: Retain key contours such as face shape, forehead, nose bridge, mouth turn, chin, ears, and hairstyle. Keep only a few essential facial features and avoid detailed carving. If the subject is a cat, dog, or other animal: Retain key identifying features such as head shape, ears, muzzle contour, eye expression, and the general outline flow of the fur, avoiding complex hair details. If the subject is a plant: Retain the most recognizable shape characteristics of the flowers, leaves, branches, fruits, or overall contours, summarizing their posture and sense of rhythm with simple lines. [Line Style Requirements] Lines must be smooth, rounded, flowing, expressive, and natural, as continuous as possible, created in one breath with a sense of breathing and improvisation. The overall design is dominated by soft curves, avoiding sharp, stiff, and rigid folded lines. Do not draw contours like a rigid logo-style trace; do not make it mechanical, stiff, fragmented, or overly regular. Lines should be simple yet vital, with a touch of casualness and artistic temperament, looking effortless, agile, and collectible. [Composition and Avatar Adaptation Logic] The overall composition is designed in a 1:1 square format. The subject should be clear, concentrated, and eye-catching, suitable for use as a social media avatar. The subject is recommended to be centered or slightly off-center, with complete contours and a clear visual center of gravity. Please reserve reasonable negative space to prevent the subject from being too large and touching the edges, ensuring that even after a circular avatar crop, key parts of the subject remain complete, clear, and highly recognizable. The image should remain simple, powerful, and easy to recognize even at small sizes. [Background Color Logic] Background color should not be fixed to a single color, and should not default to blue. Please prioritize extracting a "dark-toned logic" suitable for the background based on the overall color temperament of the input image itself, choosing an appropriate background color from the dark tendencies associated with the subject. If the user explicitly specifies a background color, use the user's specified color with priority, and on this basis, maintain an overall premium, restrained, and tense dark-toned treatment. Background color selection should follow these principles: - Dominated by dark, pure, emotionally tense solid backgrounds. - The background should effectively set off the lines of the subject, creating a clear contrast. - Do not fix on a single hue. Choose dark tones flexibly based on the image temperament, such as dark blue, dark green, dark purple, dark brown, dark gray, wine red, ink black, blue-gray, olive dark, etc. - If the image itself is suitable for a cool background, adopt a cool dark logic. - If the image itself is suitable for a warm background, adopt a warm dark logic. - If the user specifies a color, choose a calmer, dark version of that color more suitable for avatar display. - Avoid fluorescent, cheap, and overly bright sensations. - Avoid dull, dirty, low-contrast, or lifeless backgrounds. [Subject Line Color Logic] It is recommended to use white thin lines or light thin lines that contrast sharply with the background for the subject's main contour lines. Lines should not be too thick, nor too thin to lose presence; they should be light, clear, and clean. If the background is dark, prioritize white or light warm white lines to enhance recognition and crispness. [Embellishment Element Logic] Add a small amount of random, improvised, and natural small colored embellishment elements around the subject to enhance soulfulness, fun, and effortless charm. Embellishment elements can be: small dots, small arcs, small stars, small smiley faces, small short brushstrokes, small lightning bolts, simple geometric symbols, etc. The embellishment style should be rounded, playful, loose, and natural, like casually added inspirational decorations rather than deliberately typeset template elements. Embellishments must be properly controlled: - Minimal quantity, just enough to make a point. - Distributed naturally with a slightly random feel. - Do not make them too dense or too strictly symmetrical. - Do not let them overpower the subject. - Exist only as an auxiliary atmosphere. - Embellishment colors can be extracted in small amounts from the adjacent or complementary color logic of the background, or use a few pop colors such as yellow, orange, pink, light purple, light coral, etc. - The overall embellishments must coordinate with the subject and background, avoiding a stiff collage look. [Overall Style Goal] The overall image should be minimalist, light, modern, agile, and artistic. It should possess both the cleanliness of single-line illustrations and the looseness and vitality of impromptu doodles. Make the subject appear rounded, expressive, and full of soul, rather than stiff, dull, or templated. The final effect should be suitable as a social media avatar: striking, recognizable, interesting, and well-designed, while possessing an easygoing, natural, vivid, and collectible artistic temperament. [Avoided Issues] No realism, no shadows, no light and shadow volume, no complex textures, no complex scenes. No mechanical tracing, no stiff rigidity, no sharp and harsh lines, no over-regularity. Do not fix the background color to a single blue template. Do not make the background glaringly bright, and do not make it dull and lifeless. Do not over-decorate; do not take attention away from the subject. Do not lose soul due to minimalism, and do not lose restraint due to decoration. Aspect ratio 16:9 Theme: City Wander Portrait Ratio: 4:5

Model and parameter tips
GPT-image-2：Excellent for Chinese understanding, text layout, and complex graphic relations. When generating avatar visuals, describe the subject, frame, and purpose explicitly.
Midjourney：Great for strengthening stylistic mood and composition reference. You can append aspect ratio parameters, though Chinese text stability may fluctuate.
FLUX：Excellent for clear subjects, photographic textures, and graphic structures. Describe using natural language, reducing platform-unrecognized command parameters.
How to improve weak results
If the subject of "GPT2 Minimalist Line Art Avatar Optimizer" is not prominent, write 'main visual centered', 'clear outline', 'large negative space', or directly name the core object.
If the style drifts, adding 'minimalist style', 'high contrast hierarchy', and 'clear textures' is more effective than just adding emotional words.
If the image gets messy, cut background elements, edge annotations, decorative symbols, and subtitles first, leaving only the most important layer of information.
If the portrait looks like a cutout sticker: add realistic edges, natural shadows, skin details, and depth of field occlusion.
If colors are off, describe the main color, background color, brightness, and saturation clearly, avoiding vague terms like 'premium feel' or 'atmospheric'.
If the aspect ratio is wrong, change it to 1:1 / 4:5 / 16:9 / 9:16, and reduce the density of small text accordingly.
