Ain't I brave, speaking up.  I'm such an 
artiste...

At any rate, what I see with the eyes is what I 
think you would describe as a perspective 
problem.  The eye on our left (his right eye) is 
turned slightly away from us, yes?  So having it 
exactly as wide on the outside as on the inside 
just looks wrong.

Since things farther away diminish in size, the 
upper and lower line of the eye should converge 
toward some imaginary vanishing point way off to 
the left of your picture.  (there, I've exhausted 
my technical art knowledge)

In otherwords, you need to move the outside 
corner of the eye line UP, what, maybe an eighth 
of an inch?

God.  6:30 a.m. and you wouldn't believe how many 
typos I had to correct.  More Coffeee....
