Dark Raph Sketch Trade

Sketch trade with LoveableHothead, she requested Dark Raph and I tried to deliver though it might be a little hard to tell the difference from "normal Raph" when it's not a fully colored piece.
I've been having an art block and it still shows but I'm glad I got this done pretty fast. I was planning to try out some new markers a friend gave me but I just REALLY didn't feel like doing so in the end. I'm not feeling inspired at all and it suuucks.
