This is an Illustrious style lora for Skallox from DC Comics. He is a member of the Red Lantern Corps.
A weight of 1.35 to 1.5 works well with this with most models. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 3.5 to 7.5.
Prompts for this lora are ( Skallox, muscular, monster, ).
Sometimes adding additional prompts like ( brown head, goat head, brown goat head, ) or similar can help make the character since some checkpoints keeps trying to make a normal humanoid looking skull look instead of the subtle goat looking alien look.
