I've been watching MegasXLR among several other cartoons as of recent. I can't believe I skipped out on this one during it's original run. It's awesome! I really like the alien designs. I found myself sketching a few of them but this one was my favorite. He's a junkyard alien who as far as I know only appears in one episode.
Thought I'd try using a white color pencil against the dark grey markers for a reflection effect.
