I really like how you framed the subject. The colors are nice and crisp as well. I've not entered a free study, and this is why. (lazy reason, but oh well.) Nice image, very pleasing to look at. Not a 4.7, imo.
This deserved a better score than it received. I gave it a 6 during voting. I like how the leaves framed the duck and you can tell the duck is white. Also, what made the duck stand out was because of the vibrant green in the leaves. It is a very nice photo.
