I was out yesterday morning photographing ducks on a loch, when a mute swan came into another swan's territory. I managed to capture this shot as the swan attacked.

Thanks for having a look

I like the display of behavior with the water film, but the OOF swan is distracting and comp. is too centered. IQ isn't great, image is a bit dark, soft and some noise shows in the darker parts.

Cool interaction! I like what you were trying to do here, but as Arash pointed out the OOF swan is somewhat distracting and the low light presented some challenges for you.
