Overall, I like the angle you've taken with this image. I think it shows good compositional skills and everything is nicely exposed and sharp. What I'm going to say next is strictly a matter of personal taste/opinion and artistic choice. There's no "right" or "wrong" or "better" here, and many here obviously already like your picture as it is ---- but I am asking myself if the single upright pole and extraneous birds really add anything to the power of the image. You've got such a nice curved line with the perched birds . . . I wonder what the image would look like if you cropped out the right portion up to and including the pole with the two birds, and cloned out the horizontal white pipes - just leaving the curved line of perched birds - which after copping/cloning would create a nice diagonal sweep for one's eye to follow, almost from the bottom right to top left? Just something to consider.
