Camera Work/Technical: My eyes are immediately drawn to the catchlights in the child's eyes, which is initially a good thing, but the catch lights give the image an overall out-of-focus feeling, as do the other highlights on the image. This may have been a result of your post-processing. I have found, through much trial and more error, that a better result is usually yielded by running Neat Image before any sharpening is done. I'd also like to see a little more contrast to the image.
Lighting: Nicely lit, but I'd like to see the entire catch light in the child's right eye instead of it bleeding to the edge of his eyelid. I do like your use of lighting to isolate the child from the mother, thus making him the emphasized subject.
Composition/Content: I believe that your composition would be stronger if you had left his ear in the frame or either cropped a little closer to his eye.
My Opinion: Excellent job meeting the challenge. I definitely get a feeling of love as soon as the image loads. I think with more crisp focus and a little more contrast, this one would have finished even better.
I think it would get a higher score if the baby was a little more in focus. All your attention starts there and I think it should be the 'crispest' (I'm not even sure that's a word) part of the photo. Still giving high vote.
