For best outputs and usage:

Sampler: Euler a.

Steps: 30, cfg 7.5, CLIP skip 2.

VAE: none required.

Pos prompt: start it with "score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, realistic". The "realistic" keyword doesn't actually create realistic outputs, but it gives them a nice charm.

Neg prompt: "grayscale, long neck, 4 legs, bad quality, blurry, child, ugly, teeth, out of frame, red anus".
