Nice pic, but it seems to be a little soft around the head. More dof would have helped to get the whole duck in focus. I like the crop and pose. Well done.
I like the pose and low angle. Focus may be on the breast, but hard to say for sure at such a small size (you may post up to 1024 horizontally as long as the image is kept under 200kb.) I do find the WB too yellowish. For the repost I just added some blue and cyan in "Color Balance":
