Shaping the head...Feet?!

I want to change the shape of the head because its looking a bit thin at the back, I've taken it into Photoshop to draw over it to how I want it to be. Now I can see where I will pull it out and shape it off more

I was looking into not doing feet to 'fit in' with the clay look, but as i had some time, i thought i'd give it another go and i am actually really happy with how they turned out!
