Even for a big slow flying bird like this one, you did well to freeze the action as much as you did. I generally shoot for at least 1/1000s for swans, and you certainly could have traded ISO and aperture to give yourself a bit more margin here.
I like the giant yellow feet, flying drops, full up wing position.
Just for personal taste, I might be tempted to trim back the edge of the ice where it comes so close to the swans head.
