I get that it's supposed to be busy and stuff, but the character in the middle is sort of lost in the composition, and there's nothing to really lead the eye anywhere other than maybe the tongue and the giant hand. In a composition like this I think it'd be cool to have some sort of continuity leading the eye around the canvas.
I also think it might be a good idea to be more economic in your use of color, value and level of detail. If everything's equally detailed and busy, then nothing seems detailed and busy. By adding areas where not much is going on, you'll be putting more emphasis on the areas where shit's happening, making it pop even more!
