Ken:
Nice color coordination between the heron's head/neck and the termite mound.
Sharp and well exposed. If you could have taken a frame so that you were just a bit more to your right, and the bird would favor you with his head a bit more your way, it would have been even better (no background merge)
I might try cropping down about 1/3 of the free space at the top.
I generally would agree about a crop up from the bottom, but the termite mound really establishes this birds environment, and I guess I would be inclined to leave most of it! Just personal preference for me.
