Coming back to my sculpt with fresh eyes, I decided that it needed a little reshaping. Thankfully the transpose tool and move topological tool made this fairly easy to do. After fixing the shape of the face, i began to work on the neck. I did thins by masking off the face and pulling out the bottom of the skull out to form the basic shape of the neck.
After doing this, I decided I wasn’t happy with the shapes of the eyes and so began to fill the holes where they had been and block them out again. The proportions of her face seem to be a little off when I add the eyes, and I’m not sure how to correct this. Hopefully as I work on it more and get closer to the end result this will begin to rectify itself.
