芭蕾舞者粉尘人像

生成一张 4:5 竖版芭蕾舞者粉尘人像。中国女性芭蕾舞者穿无标识浅灰练功服和白色软鞋，在纯黑影棚中做一个轻盈跃起动作，双臂形成柔和弧线，脚尖离地，身边有细腻白色粉尘被动作带起，形成半圆形轨迹。构图为全身动态，人物位于画面中央，下方留出落地点，背景纯黑无文字。灯光为侧后方强轮廓光和正面弱柔光，粉尘边缘发亮。色调黑、白、浅灰和少量肤色，优雅有力量。70mm 镜头，人物比例真实，四肢自然，不要压扁。画面内不要出现任何可读文字、logo、水印、品牌、舞校名或地面标识。

Create a 4:5 vertical ballet dancer powder portrait. A Chinese female ballet dancer in an unbranded light gray practice leotard and white soft shoes performs a light airborne movement inside a pure black studio. Her arms form soft arcs, toes off the ground, and fine white powder stirred by the motion creates a semicircular trail around her. Full-body dynamic composition, subject centered with space below for the landing point, pure black background with no text. Lighting: strong side-back rim light and weak frontal soft fill, making the powder edges glow. Palette: black, white, light gray, and small skin tones; elegant and powerful. 70mm lens, realistic proportions, natural limbs, no compression. No readable text, logo, watermark, brand, dance-school name, or floor mark anywhere.
