Dude...did you seriously just recreate a locked topic? That's not cool.
Anyway, you've got OK shading skills, but the drawing itself is kind of...crude. I don't recommend you try to wow us with an entirely new version of Sonic. For that, you need tons of patience, skill, and downright genius. Remember that a million bazillion other people have tried this before you. It'll take a LOT to succeed where those million bazillion have failed.
If you're serious about it, though, go for it. Who knows? You might really impress us. But, judging from that frame, you have a looooooong way to go.
