夜间城市健身人像

Create a cinematic low-light fitness portrait of a confident young woman sitting on modern concrete stairs outdoors at night in a moody urban environment. She is centered in a vertical 2:3 frame, seated casually with one leg extended down to a lower step and the other knee bent upward, one hand resting near a stainless steel water bottle placed by her raised leg. She wears an oversized {argument name="hoodie color" default="dark brown"} pullover hoodie with loose sleeves, fitted {argument name="shorts color" default="black"} biker shorts, white ribbed crew socks with a small black swoosh-like logo, and chunky gray-and-white running sneakers. Her dark hair is tied back in a slightly messy athletic style, with a natural confident pose; keep the face softly anonymized or out of focus if needed. The setting is architectural concrete: broad gray steps, a tall concrete wall behind her, and exactly 4 warm vertical wall lights glowing along the wall, plus subtle warm strip lighting along stair edges. Background city lights are faint and blurred in the upper right. Use shallow depth of field, realistic photography, soft warm highlights against cool shadows, high dynamic range, detailed fabric texture, natural skin tones, moody cinematic color grading, 35mm portrait perspective, and no text or watermark.

创作一张电影感低光健身人像，画面中是一位自信的年轻女性，在夜间阴郁的城市环境中，坐在户外的现代混凝土台阶上。她位于 2:3 纵向画幅的中心，姿态随意，一条腿向下伸展至较低的台阶，另一条膝盖向上弯曲，一只手放在靠近抬起腿旁的不锈钢水瓶附近。她穿着一件超大号的 {argument name="hoodie color" default="深棕色"} 套头连帽衫，袖子宽松，搭配修身的 {argument name="shorts color" default="黑色"} 骑行短裤，穿着带有小型黑色勾状标志的白色罗纹中筒袜，以及厚底灰白配色跑鞋。她深色的头发扎成略显凌乱的运动风格，姿态自然自信；如有需要，可将面部进行柔和的匿名处理或虚化。背景为建筑混凝土风格：宽阔的灰色台阶，身后是一面高大的混凝土墙，墙上有 4 盏垂直排列的暖色壁灯发出光芒，台阶边缘有微妙的暖色灯带。右上角的城市背景灯光微弱且模糊。采用浅景深、写实摄影风格，冷影中带有柔和的暖色高光，高动态范围，细腻的织物纹理，自然的肤色，电影级的阴郁调色，35mm 人像视角，且画面中无文字或水印。
