Isn't it great to be able to see these creatures out in the wild? I love it. Hard to get their shots. Your focus is spot-on, and I love the reflecting water. I would like to see the cormorant in full detail, not just his/her silhouette, but that would probably have been impossible from your position. What I think would give this image a little bit more impact than it does at the moment would be a tighter crop. The cormorant is the main subject of your photo, yet it is overpowered by the water and the shoreline a bit.
