uggested settings:

I had CLIP skip 1 on every image

Samplers : Eular A, DPM++ 2M

CFG : 5-6

I had ENSD: 31337 all of them

All of them had highres.fix or img2img at higher resolution.

I don't use restore faces

I use afterdetailer for face details

Tiled diffusion for img2img upscaling and sometimes Noise Inversion for some more extra details.

4x-Ultrasharp upscaler
