I asked Jacob (color/lighting guru, and longtime crony) for some critique on one of my pieces, and he obliged, with a quick Photoshop overlay:

My original is on the left--and you can see how flat it looks in comparison to Jacob's fix on the right. He didn't make any huge changes, but the results are pretty dramatic.
Anyways, Jacob and I got to talking, and we decided that we'd both try our hand at coloring the same piece of art (line art provided by me), for a little joint blog action. The subject is Bowser:

I think both versions turned out well, but something about Jacob's colors really make my line art sing. Check out Jacob's blog to see more of his excellent art... DO EET!
