滑板少年人像

生成一张 4:5 竖版滑板少年人像。中国高中年龄少年在黄昏户外混凝土滑板场，穿米白连帽卫衣但无文字图案、深蓝牛仔裤、黑色护膝，坐在弧形碗池边缘，一只脚踩在无标识滑板上，旁边有空旷滑板坡道和夕阳长影。构图为七分身环境肖像，人物位于画面下方，背景可见滑板场曲线和远处树影，不是影棚。光线为黄昏暖光加天空冷蓝补光，色调混凝土灰、米白、深蓝、暖橙。健康青春、真实纪实摄影，35mm 镜头，人物比例真实。画面内不要出现任何可读文字、logo、水印、品牌、涂鸦、贴纸或场馆标识。

Create a 4:5 vertical portrait of a teenage skateboarder. A Chinese high-school-aged boy is at an outdoor concrete skatepark at dusk, wearing a cream hoodie with no text or graphics, dark blue jeans, and black knee pads. He sits on the edge of a curved bowl, one foot resting on an unbranded skateboard, with empty ramps and long sunset shadows nearby. Three-quarter environmental portrait, subject placed lower in the frame, skatepark curves and distant tree silhouettes visible in the background, not a studio. Warm dusk light plus cool blue sky fill; palette of concrete gray, cream, deep blue, and warm orange. Healthy youthful real documentary photography, 35mm lens, realistic proportions. No readable text, logo, watermark, brand, graffiti, sticker, or venue mark anywhere.
