American adult model Sana Fey

Not entirely happy with this one for purely photorealistic results - does a fairly good of producing her likeness with digital painting styles. Might go NSFW if you don't negative prompt to stay clear.

Recommended weight from my tests: between 0.8 and all the way up to 1 - most of my sample images were using a weight of 0.95.

I ran most of my test images using DPM++ 2M Karras with 20-28 steps, a CFG scale of around 5 using ADetailer with its default inpainting settings for faces at a base resolution of 512x768 upscaled 2x with different settings depending on the style.

Other settings may work better or worse - feel free to share yours!
