WIP Tim Green Hulk Color

Here's my first attempt at coloring using Photoshop CS5. I chose something with less linework than my typical art, but still one piece I wanted to try coloring, that of Tim Green's Hulk, that others would note, I previously inked.

While critiques are okay here, please realize that ANY coloring work I do here I KNOW is purely amateur, and that while I'd love to see what real colorists can do with any of my works, I know I'll never be able to color an entire piece, backgrounds and all because I'm just not "talented enough" to do so...or maybe it's a laziness thing?
