Very nice shots! I'll say a few things that would make them even better, since I happen to love wildlife and nature photography.

One last note, besides the behavior rule, the other biggest rule of wildlife and portrait/people photography is to focus on the eyes. By doing so, it makes the viewer feel as though they are connecting with the animal/person, and people are naturally wired to first look at someones/somethings eyes, so it only makes sense to focus on the eyes!
