I have to say the skin on her abdomen is very, very good.
For now I would forget everything else and  just concentrate on the eyes as they seem to need the most work doing. Would it be wrong of me to suggest to actually start the eyes again from scratch, with new resources & textures? I've found when creating something that when I continually try to improve a certain aspect of my work it just ends up getting too frustrating & starting afresh brings new approaches.
