I like. It's dynamic, nice diagonal composition. Might appear less cluttered if shot goose at waterline, not including two heads in foreground and substitute with a bit more water at top of frame. It would cut the bird at bottom left a bit, but to me the two in front perspective are more interesting, and you'd have gotten most of the bottom left bird. It's a minor thing, just a possiblility. I like the photo a lot!

Awww! Shame you didn't frame (and move) further to the left! having the little kid there with the birds coming in would have been great!
