Dan, this image very much appeals to me!! It's has an almost abstract quality to it. If it were mine, I would tone down the white highlights on the birds, and the lighter areas in the background - esp. the one along the left bird's neck and beak.
Very interesting image, I like the blurry look with all those curve of the bird which gave me an artistic/abstract feeling. I might have a little more room on the left since the beak of the bird there is almost touching the frame edge. Or another idea is to crop more from the right and the beak of the right bird more near the frame edge.
