They are heroes in a half shell... and all the letters of the alphabet. Now up for voting to become an officially licensed shirt at Threadless.
I decide to take another swing at the Teenage Mutant Ninja Turtles alphabet, adjusting some of the designs that I wasn't too pleased with the first time around. All of the characters here have at least minor tweaks, mostly by giving them more detail and/or shading. I was also pretty happy to find Quarry as a new Q since I really didn't like my original choice. Still a bit disappointed that I had to choose between Shredder and Splinter though.
