I don't think that I ever put the refs of the things here but here we go.
Art is from 2016-2017 and some details may have changed but nothing too critical so it's good enough for now, creatures themselves are very much recognizable.

This is Sloth pretending to be a salkahi. Otherwise okay disguise but imagine looking at someone's eyes and them looking more like flawless doll eyes rather than squishy wet fleshballs. Mildly unsettling at close, works from further distance. (Floating crown is not part of actual appearance, just drawing them just to show that hey this is one of the things.)
As per usual procedure, here are all the guys [gender neutral] in same post.
Due to the actual main reference sheet being traditional art, it has apparently confused people all these years so I finally yielded and made simpleish plain flat color versions for clarity. These are supposed to go with actual ref sheet so focus is on flat colors (and material placements).
I want to say that I absolutely don't require any exact hues, like, just do something along the guidelines. I make only traditional art and there's no hex codes or flat coloring comparable to digital flat, I don't require that. But hopefully this helps to figure out how to color a sin, since ref sheet images are heavily shaded and textured.

Pride - Envy - Wrath - Greed - Sloth - Gluttony - Lust
Sloth has green boba.
All my sin named creatures with monochromatic coloring and in weird funny poses - the collection.
It was kinda therapeutic just stretch their anatomy a bit and draw technically cool creatures in unflattering poses.
Traditional painting portrait series of my sin named creatures from 2021. Took a long while to make but glad I did.
