Minimalist Line Avatar Art

Please convert the input image into a minimalist single-line illustration suitable for social media avatars, with a default aspect ratio of 1:1. The subject can be a person, cat, dog, other animals, or plants. Based on the type of subject input, automatically extract the most distinctive external contours and key features, and summarize them as artistically simple line portraits or figurative illustrations. The overall goal is not mechanical outlines, but to preserve the main character's charm and recognizability, reconstructing single-line lines in a more sophisticated and spirited way. [Subject Processing Logic] If the subject is a person: keep key contours such as face, forehead, nose bridge, mouth curves, chin, ears, hairstyle, and only a few essential facial features, avoiding detailed detailing. If the subject is a cat, dog, or other animal: keep key identifying features such as head shape, ears, mouth and nose contours, eye expressions, and the large fur contour pattern, avoiding complex fur details. If the subject is a plant: retain the most recognizable morphological features of flowers, leaves, branches, fruits, or the overall outline, and summarize its posture and rhythm with clean lines. [Line Style Requirements] Lines must be smooth, rounded, expansive, bold, and natural, as continuous as possible, completed in one go, with a sense of breath and improvisation. The overall design focuses on soft curves, avoiding sharp, stiff, or rigid folds. Don't draw the outline in a rigid logo-style outline, avoid mechanical, stiff, fragmented, or overly rigid. Lines should be simple yet lively, with a touch of casualness and artistic flair, making them look relaxed, lively, and collectible. [Composition and Profile Picture Adaptation Logic] The overall composition should be designed in a 1:1 square format, with a clear, focused, and eye-catching subject, making it suitable for social media avatars. The main body is recommended to be centered or slightly centered, with complete contours and a clear visual focus. Please leave reasonable blank space to avoid overly large main body edges, ensuring that even after the profile is cut into a circular shape, the key parts remain intact, clear, and highly recognizable. The image should remain simple, powerful, and easy to recognize even in small sizes. [Background Color Logic] Don't fix the background color to a single color; don't default to always blue. Please prioritize the overall color temperament of the input image itself to extract the "dark tone logic" suitable for the background, and select the appropriate background color from the subject's relevant dark color tendency. If the user clearly specifies a background color, prioritize using the user-specified color, maintaining an overall high-end, restrained, and tensiony dark tone treatment on this basis. The choice of background color should follow these principles: - Mainly use a dark, pure, and emotionally charged solid background - The background should effectively highlight the main subject's lines and create a clear contrast - Do not fix on a single hue; flexibly choose dark tones such as deep blue, deep green, deep purple, deep brown, dark gray, burgundy, ink black, blue-gray, olive dark tones - If the image itself is suitable for a cool background, use a cooler dark color logic - If the image itself suits a warm background, use a warm dark color logic - If the user specifies a color, On top of this color, choose a darker version that is more stable and suitable for portrait display—avoid fluorescent or cheap, vivid looks—and avoid dull, dirty, low-contrast, and lifeless backgrounds. [Main Line Color Logic] For the main contour line, it's recommended to use white thin lines or light-colored thin lines that contrast sharply with the background. Lines shouldn't be too thick or so thin they lose their presence; they should be light, clear, and clean. If the background is darker, prioritize white or light warm white lines to enhance recognition and freshness. [Decorative Element Logic] Add a small number of random, improvised, and natural small colorful accents around the main body to enhance spirit, fun, and relaxation. Decorative elements can include: small dots, small arcs, small stars, small smiling faces, short strokes, small lightning bolts, simple geometric symbols, etc. The accent style should be rounded, playful, relaxed, and natural—like a randomly added inspirational decoration, not a deliberately typeset template element. Accents must be properly controlled: - Few and only a few touches - Natural distribution, slightly random - Not too dense, not overly symmetrical - Don't overshadow the main - Exist only as a supporting atmosphere - Accent colors can be extracted in small amounts from the logic of adjacent or complementary background colors, or use a small amount of contrasting colors such as yellow, orange, pink, light purple, light coral, etc. - The overall decoration should coordinate with the main subject and background, avoiding a stiff collage [Overall Style Goals] The overall composition should be minimalist, light, modern, dynamic, and artistic. It combines the cleanliness of single-line illustrations with the relaxed and vibrant energy of improvisational graffiti. The subject should appear smooth, expansive, and full of charm, rather than stiff, rigid, or template-based. The final effect should be suitable for social media avatars: eye-catching, recognizable, interesting, and design-oriented, while also having a relaxed, lively, natural, and collectible artistic temperament. [Avoid Issues] Do not be realistic, do not use shadows, do not use light and dark volumes, do not create complex textures, and avoid complex scenes. Don't use mechanical outlines, don't be stiff or rigid, don't be sharp or harsh, don't overly rigid. Do not fix the background color into a single blue template. Don't let the background be too bright or glaring, nor should it be dull and lifeless. Don't overdecorate or overwhelm the main body. Don't lose your spirit because of minimalism, nor lose restraint because of decoration. Ratio 16:9
