Use the uploaded reference image strictly as the sole basis for the subject. Preserve its most recognizable silhouette, expression, pose, and signature details. If there are multiple subjects, retain their relationships. Do not trace mechanically or add arbitrary elements.
Create a minimalist, expressive East Asian ink sketch, shaping the subject with only a few essential brush gestures. Every stroke must serve structure, movement, or rhythm. Let the brush lines vary naturally in thickness, with fluid changes in pressure, subtle dry-brush gaps, and variations between wet and dry ink. Allow a few long, slender curves to extend naturally along the form and movement, graceful without losing structure. Do not add meaningless looping lines. Deliberately omit redundant contours and suggest much of the form through broken lines and negative space, so the subject seems to emerge naturally from a few flowing ink lines rather than being completely outlined.
Use black ink as the structural foundation, with one or two representative colors extracted from the original image as localized accents. Vermilion or dark green may be used when appropriate to the original hues. Do not fill large areas with color. Use an off-white xuan-paper background with extremely subtle paper texture, generous blank space around the subject, and no complex background. Add one small vermilion seal in a corner. Its inscription should be an evocative phrase of two to four Chinese characters that suits the subject's character; do not invent a person's name. Include no other text.
The subject should be instantly recognizable, with few but precise strokes: tension in stillness and a lingering sense of movement. Omit decoration rather than sacrifice structure; retain a sense of incompleteness rather than piling on details to make the image feel finished.
严格以我上传的参考图为唯一主体依据，保留最具辨识度的轮廓、神态、姿态与标志性细节，多主体时保留彼此关系，不机械描摹，不随意增添元素。
极简东方水墨动态速写，仅以少数关键笔势完成主体塑造，每一笔都承担结构、动态或节奏功能。毛笔线条粗细自然，提按流畅，略带飞白与干湿变化。少量修长曲线顺着形体与动作自然延伸，飘逸而不失结构，不添加无意义的绕线。多余轮廓主动省略，大量形态通过断线与留白暗示，让主体像由几笔流动的墨线自然形成，而非被完整描边。
以黑墨为骨架，从原图提取一至两种代表色局部点睛，色相适合时可用朱红或墨绿，不大面积填色。米白宣纸底，纸纹极轻，四周大幅留白，无复杂背景。角落点缀一枚小型朱红印章，印文取二至四字贴合主体气质的意象词，不臆造姓名，无其他文字。
主体一眼可辨，笔画少而精准，静有张力，动有余韵。宁可省略装饰，不牺牲结构；宁可保留未完成感，不以堆满细节换取完整。
