One of my shortcomings as I try to make busts like this one is that I cannot fully articulate skin very well--so what I have ends up something like macabre because I focused too much on the anatomy of the muscles. What you have here is an understanding of several layers as they clothe each other. Your attention to the 360' nature of the sculpture is amazing--I could for sure roll this down a hill and have it retain its integrity. And as a previous comment mentioned, the skull is beautifully constructed--my instructor always insisted that I pay attention to the area behind the ears that usually gets neglected size-wise--your proportions are marvelous. The slope of the side profile of the face is also something that I envy in your ability to get the shape just right at that angle--the jut of the chin and the slightly boomerang curve between it and the forehead. This is all not to mention your photography skills, if it was you that took the picture: the attention to lighting, brights and darks, and perspective are really very nice. So much win.
