not an easy shot to expose for, the subjects are too dark. I would suggest that you zoom into the 3 birds or 4 birds in the foreground leave the fifth bird out as far as composition goes - drop to a lower shooting position could also improve things a little- 5
I really like the idea behind the shot. It could be my monitor, but I am losing the color in the dove on the right. It is more shape that it is definition. And also just beyond the first set of bricks I am getting almost blown out by the path there. Still a great idea and I really like your thought process on the shot.
