This is the new version on the next day. It took 15 minutes (and I was talking on the phone).
The positions of the heads are ok. The shapes are not too good yet. First time I also noticed the things around their necks, that add considerable volume. The chair I couldn't really remember, this one is way to high and has a pointy shape, which I definitively made up. The feet of the body are in good position. The position of the scissors is in the line of the hand. There is a lot of subtle head positionings I didn't seem to be able to depict fully. There are lines between the face of the teacher and his left hand the bodys left hand. same goes for the right hand.
