This is an Illustrious style lora for the character Ultron from Marvel Comics. Specifically the look of Ultron dressed as Santa Claus in a Marvel Comics Christmas special. There wasn't much to work with, and it was probably a short story, so the result is some what limiting.
A weight of 1 to 1.35 works well with this with most models with best results around or near 1. 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 ( Ultron Santron, robot, Christmas, ).
