Just a really good (if I say so myself) model of Billie done with Illustrious Realism 1.3 FP32. She is very versatile, nothing that I have tried so far has failed, and I'm getting phenomenal results even simply from text-image runs. The settings that work best after much experimentation at 27 Steps, CFG Scale 7.5 up to 9.5 and Euler A Automatic. All of the images posted are ran once through Image-Image with 1 pass of Adetailer.

If you use Illustrious Realism 1.6 Hyper try 10 Steps with a CFG of 3.5

Illustrious Realism 1.6 FP16 try 27 Steps with a CFG of 10
