The shoulders and back were a bigger undertaking! It pained me to have to cut into the areas I had so painstakingly detailed to look like fur.
After I removed the clay from the back I had to build up the armature. To do this I used balsa wood spacers cut to the shape of the back. In between the wood spacers I packed crumbled aluminum foil to bulk up the back area.
Once I had the general shape of the back done I covered it in a then layer of Ave's Apoxie Sculpt clay.
Here is a photo of the finished revision.
