This LoRA is supposed to help create a decent likeness of Madeline Kahn. I could not find too many glamorous shots of Madeline, she always seemed to prefer making a funny face, so this LoRA is not one of the easiest to make work. Use a strength around 1. Lower and it might not look that much like Madeline. Higher numbers create overtraining artifacts.
