I decided to attempt an Illustrious version for Amos Sewell to see how it would look. It was trained using WAI-illustrious-SDXL. After a bit of testing, it seems to work best using DPM++3M SDE Karras at 30 to 40 steps with a CFG of 3 or 4 but also sometimes as low as 2. The model works best with a strength of 0.9 or even 0.8 . Obviously, the more you stray from that the less the model maintains it's "look" But it still gives the base model some additional variety if you're looking for something different. It works well with the Thrasher Illustrious LoRA if you split the strengths of 0.6 and 0.5. It gives a third "vintage" look.
