A difficult one for me; personally ducks do nothing for me, so for a duck image to get me excited it has to be really special. Critique images are given out randomly so I wish you could have had someone who loves the little darlings, but those are the breaks;) That said, I do love your conDUCKtor image.
It is a sweet, inoffensive image, that would look nice on a greetings card. But, the eye of the adult duck is almost at the dead center of the image.The viewer's eye is drawn to this and then tends to stay there, creating a static image. This static element also gives the impression that the two ducks are disconnected, having little to do with each other - as if each one accidently swam into the passport photo of the other. Also their both being in the bottom half of the image, seems to cut the image in half, creating nothing in the top half for the eye to focus on.
More ducks (am I really asking for more ducks?) would have fitted the celebration aspect of your title better, but you go with what you have, when the ducks don't cooperate with our photographic vision;)
The focus is spot on: I can see the lovely colour and detail of the feathers and the texture of the soft down on the duckling's back.
another episode of Nature. Your title gives some focus to the show, though I don't look forward to an hour of ducks with their ducklings. The image is balanced but at the same time that makes it static, not very compelling. Your poster does the job, but not in a stellar fashion.
