Sweet little candid moment nicely shot and framed. You got great focus and exposure here. I think the color is a bit off as it looks really blue, especially in the whites of the eyes and in her hair. (Perhaps it is light reflected off the blue sweater but possibly the white balance.) This would transpose well to a high key black and white!
She's adorable. :-) I get the impression that you may have enhanced the blue tones somewhat, perhaps to make her eyes stand out even more...however, the image now has a heavy blue color cast to it like the white balance is off.
