I don't think the stuff in the water adds much to the shot. I would try a crop with it out (yes, I know this wouldn't be good for the challenge, but the duckling would still be pretty small :)
Such a cute duck. I love the detail in the fur. The plants on top are kind of distracting, a harsher crop should have been used to remove much of them.
Very cute! IMO the image would be more effective if the duck was completely isolated - ie no evidence of the shallow bottom. A tighter crop at the top of the frame may improve this (but may have risked low marks for subject size in this particular challange).
Hey, that's not a _rubber_ duck! Well captured, everything looks nice and sharp. The composition might be improved by isolating the duckling more, getting it away from some of the weeds and perhaps using a more extreme placement in the frame.
Nice composition, the water is wonderfully smooth and I like how you have captured the duck coming towards you – that doesn’t happen often. As a suggestion, a slightly lower viewpoint of the duck, while still capturing the weeds behind him would have made this photo stand out even more.
Generally, I hate "Duck Pictures", cus everyone does them. This one is actually quite nice. Capturing the plantlife in the background, and the ripples in the water make this an interesting image to view. Nicely done <7>
