Here is a close up of an Oriental eye. In my opinion,
eyes from the Orient have a shape commonly called "almond".
They are not round or plump-oval like eyes from the Occident
Additionally, there are three specific factors, numbered on the illustration.

1. you've got to show the fold, which looks like a
   curved line. It has to have a very specific curve.
2. the arch of the inward side of the upper rim.
   It angles down, then has a certain left-hand turn and
   points nearly straight down to the lacrimal
3. the bottom rim has a unique double curve.
   emerging from the lacrimal, it curves up in a small arc before curving back to the rim.

The images below are from my website.
I picked these specific ones because the features
of the eye are fairly clear in them.
