Very nice landing pose. You've got room to go a little brighter, which would help bring out the darks a little better. I like the way the sun is catching the eye of the flying bird.
I really like the pose of the landing heron and the reaction of the other bird...it's too bad the tip of its beak is behind its body. I agree with Doug that it could stand to go slightly brighter but even as it is now, it's an outstanding capture!
