I like the active pose, splash, foot up, wing spread. Exposure good.
The light was a somewhat harsh (dark shadows on neck ).
My biggest concern is the image rather overpowers me with all the bright detail in the background and foreground.. If possible, a lower shooting angle would have thrown the BG further out of focus, and lower in the frame.
From a comp. standpoint, I would like a bit more room on the left.
I agree with the comments, but you did a great job capturing the bird. Nice and sharp and I love the action seen here. Not always possible, but a calm day with no water ripples and debris is best to capture these guys.
