For best outputs and usage:

Sampler: Euler a.

Steps: 20, cfg 7, CLIP skip 2.

VAE: none required.

Pos prompt: start your prompt with "score_9, score_8_up, score_7_up", then what you want to see. Quality / realism words may help a little bit.

Neg prompt: "score_6, score_5, score_4, unaestheticXL_Alb2, 3d, cgi, blur, blurry, blurred face, small breasts, child, loli, underage" plus what you want to see. The embedding "unaestheticXL_Alb2" can be found in my example runs.
