中年男士从容肖像

生成一张 4:5 竖版中年男士从容肖像。主体是一位 48 岁左右的亚洲男性，站在清晨湖边木栈道上，穿浅卡其风衣、深蓝针织衫和休闲长裤，双手自然扶着木栏，看向远处水面。背景是薄雾湖面、远处树线和柔和晨光。构图为头到膝盖的环境人像，色调雾蓝、浅卡其、自然绿色，安静成熟。无文字、无 logo、无水印。

Create a 4:5 vertical calm middle-aged male portrait. The subject is an Asian man around 48 standing on a wooden lakeside boardwalk in the morning, wearing a light khaki trench coat, deep navy knit top, and casual trousers, resting his hands on the railing while looking toward the water. The background includes mist over the lake, distant trees, and soft morning light. Frame from head to knees as an environmental portrait with misty blue, light khaki, and natural green tones. Quiet, mature, no text, logo, or watermark.
