Interesting interaction here. To accentuate that, and clean up the image a bit, I would crop in from the right to eliminate the bird in the lower right. Consider cloning out some of the branches intersecting the flying bird.
the exposure looks good. There appears to be some motion blur in the flying bird.
I like the interaction and the cool pose of the crane in the air. I agree that the crane in the lower right hand corner doesn't add much to the image. If the trees and the branches in the background could be out of focus more, I think the final image could be even better.
