"en": "超写实抓拍的夜间室内生日瞬间，仅一位主体。主体面部必须与上传的参考身份达到最高保真度：面部结构、比例、眼睛、鼻子、嘴唇、眉毛、肤色和皮肤质地均须保留且不得进行美化。场景：昏暗的现代室内，带深色木质元素和几何天花横梁。服装：带细肩带、优雅垂感的浅蓝色缎面吊带裙，带有闪光质感。动作：主体双手在胸前托着放有小圆生日蛋糕的托盘；蛋糕上点着多根蜡烛。主体正在向蜡烛吹气（抿嘴，双颊微鼓）。蜡烛处发生戏剧性的火焰爆发，并向画面左侧扩散，伴有发光火花和类似闪粉的悬浮颗粒。光线：低环境室内光 + 蜡烛光高光 + 细微的机内闪光补光；真实的阴影；明亮的火焰核心；高光处有轻微光晕；皮肤呈照片写实质感。构图：主体位于右三分之一；火焰爆发占据左三分之一；背景柔和虚化。无文字、无标志、无水印。"
