I think over all it's beautiful...if i ever have children i hope someone will take something this great of my child...
Two small things though, the baby's chest is a little wrinkled due to the father's hand pushing the skin up. Second, the saggy diaper in between the baby and his father, this is distracting to me as it's very white in an otherwise beautiful shot of grays and blacks. Perhaps turning the child a bit to get his leg in the way of that would have fixed it.
Lastly from shooting infants I know it's hard to get them to look at the camera(they don't have control), and considering the blindness a little bit of noise (snapping or rattling something) can sometimes get them to glance at you/camera, but you have to be fast.
congrats on a wonderful picture he (and you) should be proud of it.
