It looks good over all, I'm certainly no expert. But it looks like possibly the head is turned a tiny bit too far to the right, I think it should be more of a 3/4 view. The shoulder looks like it could be a little too thick. All these tweaks are tiny. But over all it looks good! See the screen shot attached for a reference for the head and shoulder. [I hope I'm allowed to attach the screenshot...] : )
