末班地铁里的小提琴盒

Create one standalone 3:2 landscape image: an adult musician carrying a closed violin case through an almost empty last subway car, sodium platform light passing windows. Visual approach: telephoto space compression. Keep a single coherent scene with crisp material edges and believable spatial relationships. No collage, no grid, no logo, no watermark, and no readable text.

生成一张独立的 3:2 横幅图像：成年音乐人带着合上的小提琴盒走过几乎空无一人的末班地铁，站台暖光掠过车窗。视觉方法采用长焦空间压缩。保持单一连贯场景，材质边缘清晰，空间关系可信；不要拼贴、网格、标志、水印或可读文字。
