Excellent look at the family. Great lighting, exposure, and details. The stare on the adult is cool. Frame feels slightly bottom heavy, but I suspect that's because you don't want to add too much nest. Given the choice between that and what you did, I think you made the right decision.
Neat scene, and they do sorta look like reptiles! I like the BG and the birds. The nest seems greyed out and "flat"...perhaps you had some highlights that were toned down or some other processing there?
