Centaur CGed Picture

The Centaur drawing from my Scraps section, CGed. This is my first time CGing, and I realize that there are many inaccuracies to shading, placement, trees (I didn't spend too long on the background, if you couldn't figure out in the first place). Just taking a whirl at a first try.
