怎么填变量：穿搭写 3–4 件单品即可；背景可以换成"晴天午后的老街拐角""夜晚便利店门口"，但保留"路口 + 凸面镜"这一核心。参考照最好是清晰的正脸或微侧脸。

常见问题：

• 人物直接站在街上、看不出是镜子里：补一句"整个画面就是镜面里的倒影，镜子的红色边框在画面边缘清晰可见"。
• 脸被手机全挡住：改成"手机只挡住下巴"。
• 太精致像海报：负面提示词里的"影棚光、干净完美的镜子"一定保留。

迭代：换背景比换人物更稳，先固定人物，再逐个尝试雨天、雪天、黄昏。

Upload one portrait as the identity reference. Use it only for the subject’s facial identity, face shape, hairstyle, hair color, skin tone, and natural body proportions. Do not copy the original portrait’s clothes, background, pose, lighting, or image quality.

Create a hyper-realistic outdoor convex traffic mirror selfie, 9:16 vertical composition. The subject stands in front of a large round roadside safety mirror with a red rim, taking a flash selfie with a decorated phone case, phone partially covering the face. Use the uploaded portrait only for identity and hairstyle. Keep a casual youthful outfit: dark oversized zip hoodie, cropped white graphic tee, loose jeans, white sneakers. Rainy dusk street intersection background, wet asphalt, zebra crossing, trees, soft blue-gray sky, faint streetlights, one blurred passing scooter, dirty mirror surface with dust and water spots, strong camera flash glare, realistic fisheye distortion, candid smartphone snapshot, natural skin texture, real-life street photography, no watermark.
