The work is excellent. My only conern would be that some of the teeth seem to angle forward, which would be hard to envision from a functional perspective. Fangs tend to angle back into the mouth to catch and hold prey. Pointing outwards allows prey to slip off and makes working them into the mouth towards swallowing difficult. Unless the teeth "hinge" and shift angles somehow, like a snake's fangs do. As I said, though -- great modeling work.
