[EDIT: I've thrown out most of my old 'artwork' (including all of my old Sonic stuff that I have to hand) since it's a shambles and now I've learned how to use programs properly. >.<]
For now though, here's some of my better non-Sonic-related stuff...
My dream Kirby copy, Earthworm Kirby! If only they'd put Jim into Smash Bros....probably my oldest piece of art that I don't mind showing, this was when I was starting to get to grips with Photoshop fo' rizzle.
