The title of this image had made me smile during voting as it seemed to capture the 'expression' on the swam perfectly. Beautiful composition (talk about a cool 's-curve'), lovely detail and thewater has a fantastic soft quality to it. Great capture of the underbill too whilst still getting the splash of colour from the top of the bill
I love the angle of the neck you captured here. I think the flexibility of these animals kind of gets taken for granted. It still looks graceful, even in that twisted out yoga pose. Love the drips of water coming from the mouth and and also on the feathers. Beautiful capture of the feather details. Should have scored higher IMHO.
Because of the angle you chose and the way water against the feathers appears, this looks like an iceberg with a personality. :-) I like the swoop of the neck.
