Sonic vs. Scourge

EDIT: I fixed up Sonic's eyes, Offending Midriff, ankles and generally got rid of more of the pencil lineart. Scourge is wonderful and perfect so I didn't mess with him much at all.

Oh boy, that's a creative title (I had a really cool title, but then I forgot it).

So! Here's the result of that poll I put up. Quite a few of you wanted to see Sonic right Scourge, so I decided to take it up a notch. I made this for a contest that Archie is running at the moment. [link] Boom.

Since I've got a month 'till this picture is due, I'd love to get some feedback on how I can improve it. Thanks!
