Nice shot howard. I think its a little underexposed and could do with a little more contrast just to bring out the detail in the feathers. I really like the shallow dof and the duck in the background adds nicely to the scene. Its a shame that the reflection of the main duck is cut in half. Maybe I would have not zoomed in so close to get the reflection too and give the duck in the background a little more head space. I think the swirls in the water are a nice feature too
