Nice model! It’s very interesting the way that adjacent polygons are very different in color value. How did you generate it?

That thumbnail really tricks your eyes! I thought it was a blob.

Part of the nose is missing, and the top of the head is very interesting. Look at the eyes from the inside of the head, they look like they’re popping out at you!

Nice model. The difference of color seems to come from the normals: half of the faces have their normal inverted.
