Check out this awesome piece of geek art by illustrator David Rapoza. I came across this a day or so ago on DeviantArt.com and thought it was pretty bad ass looking. Splinter was also one of my favorite characters from the TMNT universe. Rapoza also did some great looking portraits of Casey Jones, Rocksteady, and Bebop. I’ll post those below. He’s also done some other incredible illustrations that are worth a look, like this illustration of Lion O from ThunderCats. Check out his DA gallery, or go to his website to see more.
