Minimalist Line Art Portrait Avatar

Transform the input image into a 1:1 minimalist line illustration suitable for social media avatars. The subject can be a person, animal, or plant. Do not replicate the outer appearance, describe details, or pursue completeness. Instead, extract the most essential spirit, posture, and contour relationships from the original image, conveying them in no more than six strokes. Each stroke must be a necessary expression guided by aesthetic judgment—minimal yet accurate, simple yet expressive. The lines should feel like brush or sketch strokes—fluid, rounded, and expansive, with variations in weight, pause, breath, and rhythm. Allow broken lines, blank spaces, pauses, and undulating curves, letting the image breathe naturally. Avoid mechanical outlining, fragmented contours, or templated structures. Do not depict fine facial features, hair, leaf veins, fabric folds, or aim for realism, shading, volume, or texture. The composition should be focused, striking, with ample white space, ensuring the subject remains recognizable at small sizes and in circular cropping. The background should align with the original image's mood or a user-specified color—calm, pure, and dark-toned, highlighting white or light-colored lines. Minor, subtle embellishments are allowed but must be restrained, natural, and not overpowering, harmonizing with the subject's rhythm and essence. The final result should be minimal yet powerful, loose yet spirited, with every stroke conveying the subject's expression, posture, and vitality—achieving a masterful level of abstract expression and aesthetic judgment.
