Character Head Base

Hey everyone, I’ve got some screenshots here of a project I’m currently working on. Basically this is my first real attempt at modelling anything. Anyway, this is just the base model that I’ve made so far. I’m pretty happy with how it’s coming along, but I have a tendancy to doubt myself a bit, so any and all criticism would be very much appreciated. Be constructive, mean-- I don’t really care, it all helps!
