TMNT WIP 2

After a week long hiatus, I'm back. I slapped the final colours I'm going to use on the turtles, though I am still debating whether or not to smudge it in the same vein as my Batman/Hellboy work, or to try and clean up these immaculate pencils by the great . Anything you see wrong or unusual?

UPDATE: I've chosen to go with the smudge, as I think its going very well (READ: Michelangelo).
