Henrietta, Crystalize (宵ノ境目, retro)
Infinitus21
Athreos
retro art style, cel shading, sketch style
Depending on the model, you'll get different effects, but most prominent is the retro art style coloring, grain, and also texture.
I am using it at weight 1. No need for more. Works well with WAI-ILLUSTRIOUS v14, warishita-mix, Duel-ILL-Mix, Hoshino v2. AT least those are the ones I like.
Higher weights widen the space between the eyes, which looks weird, so I don't recommend it.
You can heavily increase the retro effect by putting weights on the trigger words: (retro art style, cel shading, sketch style:1.4)
