怎么填变量：四个方括号分别控制肤色与雀斑、眼睛和表情、发型、服装，改这几处就能得到完全不同的角色，例如"[白皙皮肤，无雀斑]""[灰蓝色眼睛，表情冷淡]""[银白色短发]""[黑色高领毛衣]"。示例图是原作者生成的结果：深色丸子头、满脸雀斑、金色圈形耳环，脸部细腻，淡紫色 T 恤则保留了大块笔触。

想用自己的照片做头像：上传一张正脸照，在开头加"参考上传照片中人物的五官、脸型和发型"，其他描述保留画风部分即可；不要上传他人或明星的照片。

常见问题：

• 太像照片、没有手绘感：加"可见的铅笔线条和粗糙笔触，不要照片质感"。
• 整张都很精细，没有速写过渡：强调"肩膀以下逐渐变成未完成的线稿"。
• 想要头像比例：画幅改成 1:1，构图改成"肩部以上特写"。

适合：社交平台头像、原创角色（OC）立绘、小说封面人物、文章人物配图。
