when you rotate around the model, All the jaged edges, fix those
When you pan around the model, it should be smooth, and Flow. You can see on his cheek there, that one poly cuts off the only form of poly flow you have goin on
You need to work on making it nice and smooth. I member when eclipse told me that about ... a year and a half ago. I didnt understand at the time.
When you look at your wire frame, you should see some sort of pattern, A Direction if you will. When i look at your pikkon all i see are jaged edges Green and pink. Work on making it nice and smooth.
As for the pupils, Delete them, They arent doing anything besides making it harder for you yo work with the face. Not to mention they are a waste of polys. I usually dont even put a pupil in. Its generally skinned in, and when its not you only need the top peice of a cylender.
Hope that helps some.
