My practice object is a pony:

(Outdated image, there have been made allot of changes to the general shape of the head).
I'm going for a general pony model with cartoon shading for now. The proportions are still experimental and will most
likely change.
My next step is the eyes. Now for the well known ponies of MLP:FIM the eyes are quite important. So I want to do this right.
I thought of various approaches to make the eyes, but I have my doubts about every one of them. Here are the types of eyes
I've came up with:
- 1: The face has a 'hole' in it, slightly dented inward creating an eye socket. It's filled up with a spherical object (the eyeball).
Eyelids are the edges of the 'hole' itself, which will be a big challenge to animate properly.
- 2: The face has a slight 'dent' in it representing the eye socket. The eye is 'drawn' on it and is animated through texture options.
- 3: The face isn't changed at all. A spherical object sticks out to represent the eye.
Either separate objects, representing the eyelids, cover the eyeball or texture simulates the eyelids.
- 4: The face has a slight 'dent' in it to represent the eye socket. A spherical glass-like object overlaps the dent, behind it
(on the surface of the dent) is the eye is drawn. (think of a snowglobe with a picture on the bottom). With good camera, texture
options and lighting this would look very realistic, but it would be nearly impossible to achieve for me.
- 5: Same as #1, but with a 'glass-like' layer tightly wrapped around the eyeball itself, to give it a realistic shine.
Sorry that I can't make any quick example pictures right now... Maybe, if I find some time, I will add some quick drafts.
But my question is, what type of eye will fit the pony the best in your opinion?
