Thanks for the eye edit. It certainly stands out more as it looks larger now. Maybe some repositioning might be in order.
EDIT:
I've been working on another one. Tried to mess with the eyes a bit more. The pointy corners of piffany's edit made it look too realistic. I do like the edit though.
This one has more of a body so I'm sure there will be more comments on anatomy.

Slightly more refined than the others.

I guess I'm looking for common areas of weakness on any of these. I tend to make the same mistakes over an over and can't see them.
