Count me in.
Likes (just suggestions, do what you want):
Warm, colorful color schemes, not overly saturated but definitely not desaturated. I also like really intense contrast between two colors, i.e. a picture that shifts from yellows to blues, pinks to greens, etc, if you know the webcomic cucumber quest, it is a great example of exactly what sorts of colors I love
creative shading/clusters/colors, i.e. the reindeer dude in the op
Faces
Anatomically correct people, they're just always impressive
Ghosts
Noir Themes
Haunted mansion themes, a la luigi's mansion, scooby doo, the asthetic of the house from the movie version of clue
Mythologies of all kinds, some favorites are greek, norse, and egyptian
also: robots, nautical themes, glass, water, light, skeletons, frogs, darkness, emotions, and a whole lot of other things, so don't worry just make whatever you want to make.
Dislikes (aka, the only things I'd really not want involved):
Gore
Excessively crude humor
Needless proportion manipulation, i.e gigantic boobs
clowns/carnival themes
If you're at a loss and just want something concrete, I always appreciate interesting takes on the character that used to be my reference, back when those were a big deal
This lil' fellow, I just like seeing what people do with him
