Presidential busts

A couple of presidential busts made for a competition. They're intended for 3d printing, so no low poly versions, nor any texturing. Since I don't have a 3d printer myself, I have no idea how they will hold up when printed, but I tried to keep shapes and volumes 'articulated' enough to survive the loss of detail when printing.
