末班车里的石墨素描

Create one standalone 3:2 landscape image: a graphite drawing of the last city bus with three quiet adult passengers, reflections layered in dark windows, varied pencil pressure. Visual approach: African batik graphics. 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：石墨素描表现末班公交与三名安静的成年乘客，暗窗倒影层叠，铅笔轻重分明。视觉方法采用非洲蜡染图形。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。
