斜阳切割三角阴影的超写实肖像

4:5 竖幅大胆的超写实时尚肖像：一位成年女性化主体穿黑色西装外套与黑色高领毛衣，戴细金属框眼镜，头部向上倾斜，目光望向画外。右侧强烈的定向硬光沿对角线穿过画面，在深红橙色背景上投射出清晰锐利的三角形阴影；皮肤毛孔与织物纹理具有高微细节，电影级对比度，黑色服装轮廓清楚，色彩饱和但不过度。保持自然肤色与真实阴影；无品牌、可读文字、水印或过度磨皮。

【English Prompt】
Bold ultra-realistic 4:5 vertical fashion portrait of a generic adult feminine-presenting subject wearing a black blazer over a black turtleneck and thin metal-framed glasses. Her head tilts upward with an off-camera gaze. Hard directional light from the right cuts diagonally across the scene, casting crisp triangular shadows over a deep red-orange background. Preserve high micro-detail in skin pores and fabric texture, cinematic contrast, clear black-clothing silhouette and rich but not oversaturated color. Keep natural skin tone and believable shadow behavior; no brands, readable text, watermark or excessive retouching.
