Yes, I've been doing some spriting between other works! It's taken me a VERY long time, but now that I've kind of gotten the hang of it, I'm getting faster. I've based my Clutch sprite off of a very impressive Sonic Unleashed home made sprite sheet found here --> [link]
Needless to say, I was VERY impressed by these sprites, and it inspired me to make some of my own! I've included a comparison with his sprite as well as the sprite from Sonic 3.
