I found this is challenging, when you try to train a character who is not in common beauty standard, all well known checkpoints will pull you away from the accuracy. The solution is feed more images in the training.
Do not use "restore faces" for the accuracy.
Recommend checkpoint: SD1.5
Made this for learning AI and the freedom of art creation, doesn't mean I want to support any political groups.
Don't let the media judge your personality by like or dislike a character.
You can do whatever art you want with this.
