Here's a really nice Illustrious finetune. I've been tinkering with it for a while and I think it may be worth a post. It's illustration vibe with realistic refinement that still does illustrious things.

Recommended settings:

sampler: DPM++ 2M SDE or Euler

I rather like the first one.

CFG scale: 3 for balanced image, 5 for more contrast

steps: about 30

It's Illustrious, so use a bunch of quality tags upfront for the betterment of the output. And keep in mind that score_x doesn't do anything. Negative quality tags doesn't seem to do any good, see pinned post below,

No loras of embeddings were used for showcase images. Also no detailers or upscalers.
