Well I hate to criticize these days because some people get so upset, but if the photo is about new life I think I would have liked to have seen more space in front of her than behind her. But it's a great shot. And congrats again.
Dustin is quite right, we do need more space in from of her due to the coming future. You do often place your subjects in the middle of the frame. AND we should NOT conform to rules of thirds all the time. But in this particular photo I would have thought "perfect" if we did have just i little more room to the right for the baby and the future mini-Kris.
