Lora把发型和头发颜色固定住了，偶尔可以有不一样的发型和头发颜色，背景也基本被固定在房间里 请在Negative prompt添加”(watermark,text,username:2)“避免出现水印（但有时候还是会出现）

Lora has fixed both the hairstyle and hair color, but occasionally allows for different styles and colors. The background is mostly set in a room.
For the Negative prompt, add "(watermark, text, username:2)" to avoid watermarks (though they may still appear sometimes).
