This model is meant to attempt to replicate the works of 菲洛猫/FeiLuoMao, I do not know if they are still making works since it has been a few years, but follow them on artist sites regardless.
This model was trained using Illust ver .1 and should work on most Illust models.
Optimal Settings:
STR 1.5, CFG 5, 25 Steps, Euler A
