Nice job on your head movements, Amurphyr. But, I've got the most greatly smallest bit of advice: Why don't you do 4 minutes of 2 minute faces and expressions, pretty, pretty, please, please???? The impulse why is because, your expressions will become even more cartoonier, yet more realistic and human at the same time. I count on that it'll support and aid you even most in your next study.
