Really hard to get close to these fellows so I was really pleased to have him in for a visit, but shocked when I noticed the band. Far from a prize photo but a real keeper for me.
C & C appreciated

Dan you've got great wing position and the duck is looking at you. You need to do some CW rotation to level out your background. You may be able extend some canvas and clone in some more water and OOF grasses to fill in space.
