Transform the subject in the attached photo into a square miniature painting in a palette-knife impasto oil-painting style.
[Style — Emphasize 3D Texture]
Use bold, thick impasto paint applied with a palette knife, raised approximately 3–5 mm from the surface. Each paint mass should show clear directional knife marks, including visible grooves and ridges. Assume lighting from the upper left. Add bright highlights to raised paint and distinct shadows to recessed or overlapping areas, creating strong light-and-shadow contrast like a real oil-paint surface. Add subtle shadows along paint edges so each color mass appears layered and built up at different depths, rather than flat. Preserve the subject's silhouette, colors, and composition from the original photo, but avoid realistic rendering. Simplify the form using thick masses of paint. Keep the texture controlled and not overly detailed. The subject should remain recognizable through a limited number of bold, dimensional palette-knife strokes.
[Background]
Use a fixed warm ivory/cream watercolor-paper background with a subtle, slightly bumpy texture. Keep the background flat to contrast with the dimensional subject.
[Text]
Add a black handwritten caption in a corner along the bottom or wherever there is the most empty space. Automatically determine the caption based on the subject: Food/drink → menu name (e.g., "Pancake," "Earl Grey Cake"); Product → product name or category; Person → a short descriptive phrase or name-like text; Animal → animal name or species; Landscape → place name or a short word describing the scene. The handwriting should look naturally imperfect, slightly uneven, and tactile—not like a clean digital font. Text color must remain black.
[Composition]
Aspect ratio: 1:1. Place the subject in the center with generous negative space. Show only the main subject, with no additional props or distracting elements.
将附图中的人物/主体转化为一幅正方形迷你画作，采用调色刀厚涂（impasto）油画风格。
[风格——强调立体肌理]
使用粗犷、厚重的厚涂颜料，以调色刀堆叠，颜料高出画面约 3–5 毫米。每一团颜料都要呈现清晰的、有方向的刀痕，包括可见的沟槽与脊棱。设定光线来自左上方：抬高的颜料要有明亮高光，凹陷或交叠处要有清晰的阴影，形成真实油画表面那种强烈的明暗对比。颜料边缘补上轻微阴影，让每一团色彩都像在不同深度上分层堆叠，而不是平面的。保留原照片中主体的轮廓、色彩与构图，但避免写实渲染，用厚实的颜料块简化形态。控制质感，不过度精细；主体要通过有限数量的、有立体感的调色刀笔触保持可辨识。
[背景]
使用固定的暖象牙色/奶油色水彩纸背景，带有轻微、细小的凹凸纹理。保持背景平整，与立体的主体形成对比。
[文字]
在画面底部一角或其他留白最多处添加黑色手写文字。根据主体自动生成：食物/饮品→菜单名（如"Pancake"、"Earl Grey Cake"）；产品→产品名或类别；人物→简短的描述短语或类似名字的文字；动物→动物名或物种；风景→地名或简短场景词。手写字要看起来自然不完美、略微歪斜、有手作感，而不是干净的数字字体。文字颜色必须为黑色。
[构图]
长宽比 1:1。主体居中，四周留有充足留白。只呈现主体本身，不加多余道具或干扰元素。
