Window Side Light Calm Portrait

Create a 4:5 vertical original lighting study titled "Window Side Light Calm Portrait". Show an adult original character seated beside a wooden table near a window, body turned three-quarters toward the camera. Window side light illuminates one side of the face while the other side falls into soft shadow. Use a white linen shirt with naturally rolled sleeves, a plain ceramic cup nearby, calm expression, gaze toward the window, simple background, and natural color temperature. Emphasize light direction, facial tonal transition, fabric texture, and quiet mood. No visible text, real brands, watermarks, or garbled text.

生成一张 4:5 竖版原创光影人像图，主题为「窗边侧光平静肖像」。一位成年原创角色坐在窗边木桌旁，身体三分之四侧向镜头，脸部被窗边侧光照亮，另一侧留下柔和阴影。穿白色亚麻衬衫，袖口自然卷起，手边只有一只素色陶杯。表情平静，眼神看向窗外。背景简洁，色温自然。重点表现侧光方向、面部明暗过渡、布料纹理和安静气氛。不要出现文字、真实品牌、水印或乱码。
