Hope you don't mind Egg but I edited your post and this is what I came up with, did it differently than you, I cut out the eyes and used that shape to cut out the whites of the eyes and paisted it back in and put it to back then added the other parts of the eyes and moved them back then animated. Of course the eyes cannot follow the mouse pointer around and the pupils are fixed to the iris's as is the white reflection. The white reflections could possibly have been dealt with but I didn't.
