Hey there,

I have a thing for eyes, so i like this one aswell

It's made quite rough, which is nice in the face part but i thnik the blue of the eye could have been a bit more clean. Of course an eye has variation of colors etc, but they are quite harsh and clean at the same time. Maybe a macro shot will help you with that, if you'd like to achieve realism more

For touch ups i'd suggest using some quite strong white in the eyelashes since the lashes tend to reflect a bit of light because it's reflective a bit.

Still it's a nice piece, keep up the painting!
