The turtles have never looked so good. You can see personality in each of their faces and the beauty in the grit and grime. You are by far the best TMNT artist I've ever come across. Huge props from a true turtle fan.

Man, this is fabulous! There is one famous character missing. Krang! I can already imagine that in your style. I hope you get "muse". Great job Dave!
