The Trio of Semi-Gijinka Mobians

Got the urge to draw Rikdo Koushi's versions of Sonic and Tails (and Knuckles) again, this time on that pad of bristol board that's been sitting around for ages. It was intended to be a quick marker drawing, but you know how "quick" drawings and I tend to get along.

This would be my first time drawing S&T!Knux, and until I went over my scans recently, I'd forgotten that she has visible animal ears as well. Should note that I did have to do a Replace Colour on Sonic and Tails' skin, since for some reason, the marker I used keeps coming out way too pink/red when I scan it; the other colours came out nice and vibrant, I think.

I really want to see more unusual older doujins like S&T; any doujin-savvy folks out there who could help me out?
