For best outputs and usage:

Sampler: DPM++ 2M Karras.

Steps: 30, cfg 7, CLIP skip 2.

VAE: none required.

Pos prompt: begin your pos with "(score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up), best quality". Optionally you can use the LoRa "EnvyPonyDramaticLighting01" with a weight of 0.6 and the LoRa "Expressive_H-000001" with a weight of 1 (both found in most of my example runs). The first LoRa creates a game of lights and shadows that enhances the outputs, whilst the 2nd one enable the chance to add hearts and motion lines.

Neg prompt: this one "score_4, score_5, score_6, human face, monochrome, 3d, photo, hyperrealistic, realistic, rough sketch, fewer digits, extra digits, signature, artist name" plus what you don't want to see.
