Minimalist Cave Painting Style Avatar

Transform the input image into a 1:1 minimalist symbolic line illustration suitable for social media avatars. The subject can be a person, animal, or plant. Do not replicate the exact form, describe details, or use complete outlines. Instead, like early murals or primitive carvings, extract the most essential expression, posture, and contour features of the subject, leaving marks with a minimal number of lines. The goal is not to draw the whole subject but to create a refined symbolic image where just a few strokes reveal its temperament and charm.

The number of lines must be extremely small, ideally within 3 to 6 strokes. Every stroke should be simple, direct, and decisive, as if drawn in one go, with natural pauses and slight fluctuations. It should not be mechanical, polished, overly smooth, or form a modern logo-style closed outline. Allow for breaks, white space, and omissions to participate in the expression. Do not draw facial details, hair texture, clothing folds, leaf veins, or other explanatory details; retain only the most critical contour turns and expressive pivot points.

The overall vibe should be primitive, direct, restrained, and accurate, like a primal visual language. The background should remain simple, quiet, and steady, using a deep red, stone wall color, gray-white, dark tone, or other plain colors that can highlight the lines. The main lines should be clear, simple, and have a sense of presence. Avoid realism, shadows, volume, complex decorations, or modern graphic design styles. The final effect should be an extremely refined symbolic mark: minimal, accurate, powerful, and quiet, extracting the essence of the subject in just a few strokes.

将输入图片转化为适合社交媒体头像使用的 1:1 极简符号化线条插画。主体可为人物、动物或植物。不要复刻外形，不要描写细节，不要完整描边，而要像早期壁画或原始刻痕那样，从对象中抽取最本质的神态、姿态与轮廓特征，用极少数线条直接留下记号。目标不是画全，而是像一种被提炼后的形象符号，寥寥几笔就能让人认出其气质与神韵。

线条数量必须极少，最好控制在 3 到 6 笔 以内。每一笔都应简洁、直接、果断，像一气呵成地划出，带有自然停顿与轻微起伏，不机械，不修饰，不过度圆滑，也不做现代 logo 式完整封闭轮廓。允许断开、留白、省略，让空白参与表达。不要画五官细节、毛发纹理、衣物褶皱、叶脉或其他说明性细节，只保留最关键的轮廓转折和神态支点。

整体气质应古朴、直接、克制、准确，像一种原初的视觉语言。背景保持单纯、安静、沉稳，可为绛红色、石壁色、灰白、暗色或其他能够衬托线条的素净底色。主线条应清晰、单纯、有存在感。不要写实，不要阴影，不要体积，不要复杂装饰，不要现代图形设计腔。最终效果应像一则极度提炼的形象记号：少、准、狠、静，几笔之间就把对象的神态抽出来。
