Teenage Boy Street-Style Studio

Create a 4:5 vertical studio street-style portrait of a teenage boy. A Chinese high-school-aged boy stands in front of a light gray studio backdrop, wearing an oversized deep green baseball jacket, a plain white T-shirt with no graphics or text, dark cargo pants, and clean sneakers. A blank unbranded skateboard rests across his shoulder as a styling prop, but the scene is not a skatepark. Natural pose, both hands holding the ends of the skateboard, body slightly angled toward the camera, fresh confident expression. Full-body studio composition, clean background, soft floor shadow. Large soft light plus slight cool rim light; palette of deep green, white, dark gray, and light gray, youthful but not overly branded. Realistic proportions, healthy natural minor representation. No readable text, logo, watermark, brand, graphic, sticker, or label anywhere.

生成一张 4:5 竖版少年街头风格棚拍。中国高中年龄男生站在影棚浅灰背景前，穿宽松深绿色棒球夹克、白色 T 恤但无任何图案文字、深色工装裤和干净运动鞋，肩上搭一只无标识滑板作为造型道具但不在滑板场。姿态自然，双手握住滑板两端，微微侧身看镜头，表情清爽自信。构图为全身棚拍，背景干净，地面有柔和阴影。灯光为大柔光加轻微冷色边缘光，色调深绿、白、深灰、浅灰，年轻但不过度潮牌。人物比例真实，未成年人形象健康自然。画面内不要出现任何可读文字、logo、水印、品牌、图案、贴纸或标签。
