This could have been stunning, but, for me at least, there are a couple of issues that totally change the feel.
First what I like - the composition is good, the spare nature compliments the sad face. The perspective is an excellent choice, and really helps the viewer feel the eye contact; it also adds to the feeling of the child's vulnerability. The child's expression connects with me.
Here is why I am not keen on the photo as entered here - firstly the processing of the eyes, which become a too dominant feature. The processing here just doesn't meld with the overall photo. Secondly the bright overblown section of hair, and thirdly the change of background. These last two are easily dealt with by cropping just below the line in the background.
I sound very negative - other's may like the portrait as it is, but I personally would love to see it processed differently, more subtlely, as I feel that it is a strong base photograph
eyes are a little overprocessed compared to the rest of the picture in my opinion, to me you crossed the line between making them pop to makeing them fake
Picture is overexposed and off-center - neither of which help. Great eyes and even lighting. Try cropping it on just the face, and see if you like that (may need to rotate a bit so it is level).
