山区列车长的站台肖像

Create one standalone 3:2 landscape image: an adult mountain railway conductor on a quiet platform at first snow, navy uniform without logos, medium-format portrait. Visual approach: one point perspective. 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：初雪时安静站台上的成年山区列车长，海军蓝无标志制服，中画幅人像。视觉方法采用单点透视。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。
