I dont have a problem with her eyes, if they are slightly crosseyed I cant even really see it.
Youve actually LOST a little volume with your render, it looks like it was painted a little flat, unbelievably, but since of course its a model its volume is actually all there, maybe its just the colours are comic book style its making me think its a little flat.
Totally amazing render, with a lot of work - you could make a 3d comic book.
and boy would it have correct proportion all the time.
