It's done! Actually it would have been done a lot sooner (this is why you got a preview) but I managed to hurt my hand a bit after working extra hard on it the second day--I hold my stylus pretty tightly and after working for so long without a real break (once I get going on something like this it's hard to stop!) it started getting to me, I figured I'd better quit before I did some real damage.
Anyway, here's my latest Sonic picture! I like drawing the backgrounds so much I didn't even bother putting Sonic into this one. Thanks a lot to everyone who commented on the preview picture, and I hope you like the full version even better!
I'd like to do a second piece (making it a diptych!) showing the "city" levels, but it won't be for a while--focusing on my own non-fanart projects really takes priority! Thanks for looking everyone!
