Acorn Mix is a model suitable for any subject. It is good for realism as well as stylized/painting generations.
It is good at both SFW and NSFW.
I don't have recommendations as I havent tested the model extensively, but I find a cfg between 3.5-7 and DPM++ 2M SDE Karras as sampler give some pretty good results.
Have fun with the model and happy experimenting!
