TMNT: Lecture3

And this is a follow up to the ' pointing' pic too [link] and [link]. This wasn't going to be coloured either but that tiny pic of Don and Raph makes me laugh.
These two 'sequels' really weren't planned which is why they're a little all over the place.
I need to draw a nice normal pic now.

EDIT: Oh yeah, and the reason I have Raph getting revenge on Don and Leo on Mikey in particular is because I figured Leo lecturing Donnie wouldn't work as well.
I think Don could cope with being bored a lot better than Michelangelo and I don't think Leo would be able to wind Donnie up as easily.
