EDIT: Darkened and added better shadows. The gray colors, while showing where the highlight/shadow of the iris are, also shows if that eye style gets color. Not all eyes get shadows/highlights because they are too small for you to see them. Keep this in mind.
I was drawing my fakemon the other day, and I realized that the way I was drawing eyes was weird. So I sat down, looked at various official Sugimori artwork, and attempted to recreate the more common eye styles I saw. I think it helped me a lot.
Anyways, I thought that I should upload this. Maybe it'll help someone who's having trouble drawing Pokemon-esque eyes ^-^ But it's a good idea to do the same thing I did: go find some Sugimori artwork and copy how you see the eyes go. It took me about 3 hours to make this :l
These are NOT all the styles of eyes. In reality, there's a lot of versions that are just variations of these here... so I didn't want to end up drawing all 600+ eyes >.>

This... thing drawn by yours truly.
I can't remember which Pokemon I used for some of these x.x
oh, "Cute" means basically the popular Pokemon (i.e. Eevee, Charmander, Pikachu, etc).
