TMNT mini tutorial

At my friend Fushidane's request, I did this small tutorial.
I tried to make it as "step by step" as possible.
I hope it will be useful to all you people who want to draw TMNT.

1)shape of the upper eyes
2)finish the eyes
3)connect the two eyes (bandana)
4)shape of the nose
5)continue the bandana from the eyes and the nose
6)finish the bandana (adjust to your perspective)
7)start the shape of both sides of the head
8)draw the chin
9)add the mouth
10)draw upper head (watch out, it's not that big for the TMNT) and add bandana. Fix the overall shape of the head if necessary.
11)start the neck (large or small, depending on your style of TMNT)
12)start upper part of the yellow shell
13)shoulders
14)draw shell behind the shoulders and the neck and finish the bandana
15)lower part of the chest (yellow shell)
16)start to draw arms
17)finish yellow shell and then finish arms. (vice-versa depending on the pose). And also fix a few things here and there.

It's not finished yet, but I think that's a start, huh?
