Here's the last, sloppy and all. And as I said before, I know people may disagree with the elements I've chosen for each turtle, and that's totally okay, but please don't post about it here. :)
I think the elements you have chosen very well. Raph as firebender is a no brainer really XD Leo is the cool tactician and prefers having many options over raw power (and water is the most versatile element, being able to mimic both earth (ice) and air (mist) in a way) so waterbender fits well. Mike as airbender makes sense too since he is the "airheaded" one. Generally in good spirits, uplifting and open minded. Don is pretty much a down to earth guy and prefers to ponder actions before charging in. So yeah Earthbender is his thing ^^
And the pictures look great :3
