Framing - Very well done like the fact the you filled the frame with your subjects leaving little if any dead space.
Focus - I realize your attention was focused on the heart and hand of the child but I would have liked to have seen the childs face a bit clearer here seems a bit soft. Don't get me wrong I think works well here more of a personal preference.
Exposure - There are some hot spots most noticeable on the childs forearm and in the backgroud between mom & child, and again behind childs left shoulder.
Overall - Well done, simple warm image that makes it point.
