Here are a couple of sketches you may have seen before. Or not. I posted them on my blog last year, and was immediately summoned into the inner sanctum and asked to take them down because, at the time, I was working on the new TMNT pilot and Nickelodeon hadn't yet revealed any images from the upcoming series. Now that the curtain's been lifted, I can post them again. You can read my original post for the Donatello sketch here, and the Leonardo sketch here. The Donatello sketch also found its way onto Bleeding Cool before I could take it down, complete with a questionable (but accurate) headline.
