Here is my sculpt for the lion mask. To me, it has more of a tribal mask look to it than many of my previous attempts. Originally, it was about a half inch shallower (is that a word?) and I wanted to add some depth to it. So I added half an inch to the base and rebaked it. The second bake produced cracks around the base and down the right side of the nose. I filled the cracks around the base and baked it a third time. This should work out fine for the mold.
See the slight burn on the nose? I left it in the oven a little too long.
