I need some advice.

I am working on a head model and I am running into a problem that seems to have a recurrent theme.

The eyeball / eyelid interface does not match from the front vs. the side view. I have seen this both for drawn images and even photo images.

The side view of the eyelid/eyeball interface always seems larger then it does from the front view. Can one of the artistic gurus among you ...

(a) please explain why this front / side disparity exists?

(b) in modeling what is the correct solution:
1. model the front?
2. model the side?
3. model somewhere in between?
4. go to the bar and get drunk? :wink:

Thanks,
Rick M

see 2 attached images:

(1) Front view - green curve outlines eyeball/eyelid interface

(2) Side view - green curve outlines rough guesstimate of the eyeball/eyelid interface

I am sure some of this is the result of the stylized drawing but I have seen this effect even when I have taken digital images of a subject.
