Really cool colors you've got going on here! Primary colors always look great together but the context you put them in here is great. Blue BG/Sky, Yellow fur, red features/accessories/line art. It all works very well together. I can tell you have your own style and know it well. I think the eyes are probably the highlight though. The green pupils offer a really great pop of color. The piece is grungy in the best way.
Keep it up!
