Captureing birds isn't easy..good attempt here and better than I had any luck with. Perhaps a another angle to shoot from as they blend into the backgraound and hard to see. Hope to see other shots of these maybe.
Looks like a lot jaggies here--over sharpened? or Compression? The action is very nice, and the view is okay. I think composition could use some help or some more tighter cropping. Sometimes we try to include too much in a single shot.
