Because Splinter rules, and I like to think of him doing more than just hobbling around in a makeshift home in a sewer all day. To train ninja, you'd have to be a damn good ninja, no? Hmm, Splinter in a traditional black ninja outfit...

Relatively quick color on a relatively quick sketch. I tried to think of this like a comic book cover, though my style isn't as "clean" as those awesome artists.
