Focus seems to be off, there are a couple in the middel and to the left that appear focused and then those in front and rear do not. Large object in top right distracts.
Nice idea, but which one is the one? A different-looking duck for the primary focus would have made the shot, but as it is, focus is the only clue/cue, which probably isn't enough for most viewers. Also consider using spot illumination for more isolation of the one.
My eye had to hunt a little bit for the duck that was in focus. Once I found it, the photo came together for me more. I think perhaps a composition that accentuated the "main duck" might entice some more voters.
Focus seems a little soft. IMHO the composition could be improved. There's not a main focual point so a solid gathering of ducks with out the dark spot of nothing in the middle and right side would help.
