Greetings from the critique club. First I'd like to point out that I'm pretty sure this specimen is a goose not a duck. That may have been a problem with the voters. I like the good focus, lighting and the use of OoF background Bokeh to bring the viewer to the title and to the Subject. I think what really hurt you was the fact that you had the wrong animal for the title. Good luck in future challenges.
What I quite like about this one is if you really take a look at the duck, it looks as though his beak really, really does not go with the rest of his head. What a strange sense of humor Mother Nature has!
