Adding back of the head

The next part of the modelling process was to create the back of the head, this was done by create a large sphere and the moving it into position at the back of the face, keeping in mind the shape of my head without the hair on top, I would then remove parts of the head like the side and back that I wouldnt be using yet also keeping in mind the space for the ear, Next I had to cut the polygon count to match up to the face, after all this was done I attached the head to the face and tweaked it so a nice flow was created.

Here is the picture of the back of the head.
