I'll tried to get the looks of the characters as close as possible. I'll try to get better versions out to get the faces to look more like the characters if I can find out how to do so.

Strength recommended is 0.8 ~ 0.9

Tends to make multiple heads on character if at 1. I recommend using Adetailer and put the lora at 1 or 1.2 to make the face look more closer to the characters.
