发丝那一缕，是这张的差分点
深炭灰背景压满右侧留黑，暖琥珀高光只落在颧骨和发丝边缘。
✍️ 右侧那片黑不是留白凑数，是给壁纸模式让位置——这跟差分立绘留裁切区一个道理，位置得先想好再画细节。

Set inside a 16:9 widescreen studio portrait frame, a single woman in her early 30s gazes into the camera with a calm, neutral expression, shoulders turned slightly and hair pulled back neatly. Render the head and shoulders crisp and realistic, clean catchlights and natural skin texture intact, while leaving generous dark negative space toward the right so the image still reads well as wallpaper. A soft key light falls off gently with subtle rim separation, the deep charcoal background gradient staying minimal in detail, warm amber highlights meeting cool slate shadows, and a faint layer of film grain finishing the look.

在16:9宽画幅的影棚人像构图里，一位三十岁出头的女性直视镜头，表情平静中性，肩膀略微侧转，头发整齐地束在脑后。头部与肩膀部分处理得清晰写实，干净的眼神光与自然的皮肤质感一并保留，右侧留出充足的深色负空间，让整张图作为壁纸也能读起来舒服。柔和的主光自然衰减，带细微的轮廓分离，深炭灰背景渐变保持极简的细节，暖琥珀高光与冷石板灰阴影相遇，一层淡淡的胶片颗粒感收尾。
