Not sure where the "off screen expectation" is here. NIce shot but a little lacking in a focal point just too much going on in th etop half of the photo
I like this - very creative. I guess this was fairly opportunistic but there woudl be ways of improving here. First the birds are indistinct against their background - a lower angle would enmphasise the sense of flight. the foregoround is out of focus - given that this is where the off-screen action is (the disturbance) this might be better in focus. finally, there's a sense of chaos in the images of the birds -which is distracting. A smaller flock would have helped. Well done.
I am missing a focal point, I see a lot of wings cluttered with a brown background, which does not make a strong appealing image to me. Taken from a different angle, or concentrating on only a few birds might have been better.
