This is Blackfox, the character of another regular I knew on the Sonic Ideal Discussion Forum way back in the day. I think her character design changed significantly later on, but I thought this design was beautiful. Too bad I didn't do it much justice.

I'm pretty sure that her DeviantArt gallery is here: http://jaxxblackfox.deviantart.com/
She doesn't do much Sonic or anthro stuff anymore, but she's pretty talented.

Rest in Peace, Blackfox. You were a joy and inspiration to many.
