Beautiful shot! I love the colors and the contrast of the swan's reflection against the sun's reflection in the water (did I make sense?). There are only a few things that I feel would have made this wonderful picture even better (because I am super picky and critical). The first thing is that I wish that I could either see less of the swan's features, or more (either they be completely blacked out, or brighter). As it is, the swan's face almost looks as if it isn't in focus. Another thing, and this is something I struggle with ALL the time, is noise. On the swan's neck and body especially. I also wish that there weren't any tree branches/twigs in the way--but that is just my opinion. Other than that, the picture is really beautiful. The focus is great--everything is nice and clear, and so is the dof. Great job!
I really love this, but the composition bugs me a bit. For some reason my eye keeps wanting to land on the swan's back instead of, say, the head or something. I'm not sure why this is--perhaps the position of the swan? Maybe if the composition was longer or if the swan wasn't so near the center of the picture?
I mean, I'm not a photographer, but there are some of my thoughts. Hope they're at least a little helpful!
