SD 1,5 version.
Works without the trigger words ArsMJStyle, Art Nouveau, but gives stronger results with them.
Lower the CFG if everything seems melty. I usually use 5, but depends on the model/lora stack.
Works great in the 0.3 - 1 range, depending on the Lora Stack you use.
I recommend starting in the 0.6 - 0.8 range
Distortions are visible above 1, but produces interesting abstracts in the 1-2 range
