My book shows it the same length front-to-back, but shorter (this gives the effect of squinting a bit), and shows it with a black pupil and outline, white eyeball.
Then again, I don't know if this artwork is 100% or not.
My book's got the eye with a bit more upper arch before it reaches the point at the back, and it starts out round then arches upward and tapers back to a point. I can probably scan it for you tomorrow if you'd like? Probably inconsequential, but I offer because you said you were unhappy with it.
