四款模型生成效果对比测试

A young man in his early twenties with short black hair and a gentle atmosphere. Standing on a winter night road, wearing a dark blue coat and a gray scarf. An anime-style illustration where he is looking at a small letter or bag with a soft expression. Snow is falling quietly, and the background is the blurred light of a winter city. A gentle atmosphere, delicate lines, and a feeling of Christmas warmth.
