@ Gared - Good points. I use Photoshop 5.5 for my lettering, and reduced the strip prior to lettering, so I get that aliased look, which does suck.
The belt - didn't get into it, but it's an ancient relic he stole, and it gives him his enhanced physical power. It's supposed to appear rock-like - smooth yet very old.
The coloring - yeah - the cape was a pain. I don't think it looks right, either. But hey, when you're colorblind, you're more than happy to get that feedback.
@ drifter - I really went for an angular look, and the sides just kinda came out like that. I might clear up some of the interior details, but I like that basic shape for my character.
Thank you both for the crits!
Honestly, I probably would only continue this in black and white, with hand lettering like I'm doing with Zaptronic. The color just doesn't look right, and takes so much more time. I'm having enough trouble just scanning them in. All I have is a Viewpoint wand scanner, and while the scans themselves look good, straightening them out alone is a major pain.
