with Side shot it's heaps easyer to see.
I reckon that the bit between the eyebrows is too forward.
the eyebrows need to be pushed back out away from the face.
In the side view to the left.
Maybe the eye ball bigger, you may run into animation probs if they are too small.
A little tweekin of the nostrils, they look like they are blending into the nose a little too much.
That bit about over accentuating features is sort of cause if you model it perfect and then put a poly smooth on after it all becomes too flat, and you'll lose detail.
Over all I reckon you got poly modeling in the bag!
GREAT MODEL !!!!
