Trained this on images of the vanilla Rimworld storytellers + main manu characters

Mostly just used default CivitAI online trainer settings,

Activation text: RimWorldStoryteller

Useful prompts:

thick outlines, planet background, star (sky),

you can add "flat color", seems closer to reference images, maybe "night" "dark"

can put "anime" and/or "shiny skin" in negatives to try and get closer to reference

Hires fix + Adetailer can help a lot,

also turning down the brightness a bit, like Vectorscope extension for Forge UI

if you're getting random birds, try adding "raven, animal on shoulder, holding animal, tentacles, bird" to negatives, reference had a guy with a bird on his shoulder, also girl with tentacles on her back,
