I can't deiced on this one. The exposure, composition and IQ are all good I an just not sure on the head angle in the pose. I think is is because I am unsure what is it doing. Was it shaking the water off? If so maybe the image needs a slower shutter speed to show a little movement.
How much of a crop was used? Only critique would be the angle of light, it leaves a lot of the subject in shadows which lessens apparent detail without adding to dramatic effect. I understand how frustrating it can be to deal with what's available in the field, to that end I think you've pulled as much out of this shot as possible.
Thanks, folks. Randall, there was minimal crop - only a bit for composition. I guess a bit slower SS would have been useful to show his shake of the water, but then I'm not sure the blur on his face would have been nice.
Ian, I often face the same problem with water shots and I always like sharpness over "blur for motion". I guess I know what happened but others do have a point. I have a few loons, grebes and terns like this, but there is more water drops to "explain" the photo. In the end, I like the photo....I knew what the bird was doing immediately.
