This looks like originally it was a good capture - stopped motion, good composition, nice reflection - but it looks like it was over sharpened. I see a lot of pixel scarring.
Fairly noisy and quite soft. I'm guessing you were zoomed in and may have lost apature when doing so and so had to compromise by using a higher ISO. Well composed though, would have been better with just the single bird as the other two don't conform to the challange and are facing the wrong way
