青年毕业纪念写真

生成一张 4:5 竖版青年毕业纪念写真。中国大学毕业生穿深蓝学位袍但没有任何校徽或文字，站在校园梧桐大道尽头的石阶上，手里抱着无字毕业证书筒和一束向日葵，身后是柔焦教学楼拱门和同学远景。光线为上午柔和自然光，色调深蓝、向日葵黄、树叶绿、浅石灰，明亮纪念感。真实毕业写真摄影，70mm 镜头，七分身构图，人物比例真实，学位服不变形。画面内不要出现任何可读文字、logo、水印、校名、校徽或横幅。

Create a 4:5 vertical young graduation portrait. A Chinese university graduate in a deep navy academic gown with no school emblem or text stands on stone steps at the end of a tree-lined campus avenue. She holds a blank diploma tube and a bouquet of sunflowers, with a softly blurred teaching-building arch and distant classmates behind her. Soft natural morning light; deep navy, sunflower yellow, leafy green, and pale stone gray palette with a bright commemorative mood. Real graduation portrait photography, 70mm lens, three-quarter body composition, realistic proportions and an undistorted gown. No readable text, logo, watermark, school name, school badge, or banner anywhere in the image.
