  "prompt": "使用上传的参考图像，在零改动的情况下，保留主体精确的面部特征、比例、发型和肤色。将肖像重新构想为高端的炭笔和粉笔时尚社论艺术作品。主体可以是男性或女性；相应地调整造型和姿势，同时保持力量感、自信和优雅。面部以高度逼真的炭笔细节呈现——浓郁的黑色、柔和的灰色和精确的面部结构——而颧骨、下颌线、锁骨和头发上的高光则通过微妙的白色或暖色粉笔点缀来营造。服装通过富有表现力的炭笔笔触和色调对比来暗示，展现出西式奢华的轮廓，但没有详细的纹理。姿势强劲且富有社论感，沉静而又具有掌控力。背景极简且富有氛围感，由模糊的炭笔渐变或纹理纸张纹理构成。光线具有戏剧性和方向性，通过对比而非色彩来塑造主体。整体氛围大胆、原始、永恒且充满力量——时尚社论与美术炭笔肖像的完美结合。",

  "prompt": "Use the uploaded reference image to preserve the subject’s exact facial identity, proportions, hair, and skin tone with zero alteration. Reimagine the portrait as a high-end charcoal and chalk fashion editorial artwork. The subject may be a man or a woman; adapt styling and pose accordingly while maintaining strength, confidence, and elegance. Render the face with highly realistic charcoal detailing—rich blacks, soft greys, and precise facial structure—while highlights on cheekbones, jawline, collarbones, and hair are created using subtle white or warm chalk accents. Clothing is suggested through expressive charcoal strokes and tonal contrast, implying Western luxury silhouettes without detailed textures. Pose is strong and editorial, calm yet commanding. Background is minimal and atmospheric, composed of smudged charcoal gradients or textured paper grain. Lighting is dramatic and directional, sculpting the subject through contrast rather than color. Overall mood is bold, raw, timeless, and powerful—fashion editorial meets fine-art charcoal portrait.",
