Eric I like the light and the family grouping. I find their hooves a little too close to the bottom of the frame but I'm not sure what would have been seen if you had moved your angle down a bit more.
A real nice grouping of zebra in some sweet light. The egret is a nice touch. As Stephen mentioned a bit more room on the the bottom of the frame would help. Very nice.
The cattle egret surely adds interest to this photograph. I agree with the others that a bit more space at the bottom might have worked better here. Wonderful light and besides the little nit, nice framing!
