The heads

Black accents
,heavy use of darker values
,shifting perspectives
,lots of texture
,not vary many colors (I don't mean this in a bad way, like you have theory to it)
,saturation is mid to low

Style comes off western cartoony like 80/90s'. I can image the artwork most in a public place going for an urban feel.

It does have unique qualities that would make me be able to pick your art away from the others.

the eyes!
they have very strong expresions in it :3

The proportions and the poses.
