Well, I just picked it up.
I love your work in general, so I don't know how helpful I can be.
One thing I can't figure out is, drawn from certain angles, the Turtles seem to have an extra line drawn across their nose. Leo at the bottom of page 4 has it and Mike in the second panel of page 9 has it.
Casey in his undies...
I love that the Raph/Leo fight still ends with Raph poking Leo in the eye. Hehehe.
I love the sillouette of Leo on page 8. I also love page 20. And 46 (and 47).
In general everything is very solid, although the Turtle noses can get funky here and there with an upward point (page 30 stands out).
I definitely like seeing tidbits of the stuff that got cut out!
My biggest disappointment? That it's not in color.
