地下通道钠灯人像

生成一张 4:5 竖版地下通道钠灯人像。中国中年男性穿深灰工装夹克，独自站在城市高架桥下的混凝土地下通道中，背靠粗糙水泥柱，远处有斑驳墙面和湿地面反光，没有文字或涂鸦。顶部一排钠灯形成强烈橙黄色光池，远处有冷绿色出口光。镜头为 40mm 环境人像，七分身构图，人物偏右，通道线条向远处延伸，气质克制、安静、有城市孤独感。色调为钠灯橙、混凝土灰、深工装黑和少量冷绿。人物比例真实，肩颈和腿部不要变形。画面内不要出现任何可读文字、涂鸦、logo、水印、品牌或告示。

Create a 4:5 vertical sodium-light underpass portrait. A middle-aged Chinese man in a dark gray workwear jacket stands alone under an urban overpass in a concrete underpass, leaning against a rough cement pillar. The distance shows mottled walls and wet floor reflections, with no text or graffiti. A row of overhead sodium lamps creates strong orange-yellow pools of light, with a cool green exit glow far away. 40mm environmental portrait, three-quarter body composition, subject placed to the right, tunnel lines extending into the distance, restrained quiet urban loneliness. Palette: sodium orange, concrete gray, dark workwear black, and a small amount of cool green. Realistic body proportions; no shoulder, neck, or leg distortion. No readable text, graffiti, logo, watermark, brand, or notice anywhere.
