What stands out here is the arms and the fingers, really great curvature and composition to them. This is to me the ultimate chibi look, simplification that suggests anatomy, not a lack of anatomy.
I don't like the faces however. Lego taught us that spheres with stripes are faces and tactics games taught us that it's okay to squash the shape to an oval, but personally, I feel like there's a better shape out there.
I'd also try to make the shading angular here and there. The shape of the boots feels a little too ambiguous, more like cotton balls than shoes.
Quite interesting approach! It reminded me of one of electroclash music founders on how to make music - try to do what was done by others without fear, because you'll never do exactly the same piece.
