Good sharpness. Hard to criticize such a difficult shot, but the left overexposed and somewhat posterized area detracts from the overall effect. Also, if you could have caught the ends of the dark lashes at the top I think it would have been stronger.
IMHO your crop is too close. I think it would look better with all the lashes in the frame. I'm not sure what you are trying to say with the blue left intact, it doesn't seem to have a purpose. Your inner and outer frames are not even giving it a lopsided look.

It's hard to critique this beautiful capture. The only thing that bothers me and only a little is the whites on the left are a bit blown out and the subject is a bit too centered for my taste. If you cropped about 10% from the left of the image, it might be better.
