I like the barge effect created by the Scaup. The water drops on the head are interesting as well. I would consider removing the bright spot at the tip of the bill. Well done Mike!
loved the focus on the eye, the drops, low angle and the wave. Very nice. These fellows, because of their eyes, are very good candidates for head-on shots. Very well done.
Now this guy's got his sights on you!! Excellent theme image, I love it! The large wake in front and the "wind-streaked" drop lines on the face make this duck appear as if it is zooming very quickly in the water. Very intense photo.
