Perhaps a little overexposed? I like composition and wayward duckling. The uniform blue setting and background is a nice contrast to the yellow ducks. I hope you explain how you achieved this effect.
Very cute. I really like this. If possible try maximizing the depth of field. Perhaps your camera doesn't let you change the aperture of the lens opening, or perhaps you did this intentionally. I think it detracts from the overall picture. I would rate this very highly otherwise.
Edit: I actually like the DOF just fine like this. It works well artistically. The smooth gradation in the background colors compliment the subject, and overall a wonderful composition! Bumping up to 9.
Good idea, nice lighting dof and composition. The colours somehow don't work toghether and the border makes it hard for the ayes to focus on the subect.
Judging from your title, I'd guess you were trying to feature the renegade duck in the back, but he's out of focus. Toys and models tend to score low, but the concept is fine, and a more "serious" background might have helped.
Alltough the subjects does not really appeal to me, I have to admit that this very nicely done. Nice colours, nice lighting and great use of depth. Nice!
