Coloring again

I'm getting so rusty on my photoshop coloring, I decided to break out the ol' Wacom tablet and try my hand at coloring my 'P.A.T.R.I.O.T. vs the Liberal Zombies' piece I did many moons ago. I'm working with Photoshop Elements, which is cool because it came with the wacom tablet and didn't cost me $600 bucks, but also it kinda sucks cuz it won't let you color via channels. I bought an issue of Photoshop magazine a while back that had a rockin' tutorial on how to color using channels. Sadly, it was much easier to understand than the 'how to color comics' book I dropped $20 on  prior to finding that issue. I'm trying to make it look like a fake comic book cover. I'll post it when I'm done.
