The Great Wood Duck

Uhm, Im not a photographer but Im gonna give a constructive criticism based on my point of view as a student of graphic arts, so uh. When I first look at it I can't keep my eyes off the subject so you really did show what's the real focus on the image and the space before the duck it really shows that the subject is moving and the small water waves circling on it as it moves it really makes the subject more outstanding.. one last thing the background really blends in, so yeah!, though I can't see any flaws since Im not a photographer but from different perspective that's what it is for me and it's a picture perfect .
