女性舞者艺术肖像

生成一张 4:5 竖版女性舞者艺术肖像。主体是一位 26 岁左右的亚洲当代舞者，穿黑色无品牌练功服与裸色软舞鞋，在深灰摄影棚中做侧向延展动作，一只手臂向上弧形伸展，另一只手向侧方展开，一条腿稳定支撑。头、肩、手臂、腰和腿比例真实。背景为冷白轮廓光和地面微反光，色调黑、深灰、冷白。无文字、无 logo、无水印。

Create a 4:5 vertical artistic portrait of a female dancer. The subject is an Asian contemporary dancer around 26 wearing an unbranded black practice outfit and nude soft dance shoes, performing a side extension pose in a dark gray studio: one arm arcs upward, the other extends sideways, and one leg supports the body. Keep the head, shoulders, arms, waist, and legs naturally proportioned. Use cool white rim light and subtle floor reflection, with black, dark gray, and cool white tones. No text, logo, or watermark.
