Very nice photo and good and clear and great reflection in the water.There is no fault in this picture at all but it may have look a bit better if you had cropped it a bit tighter.But saying that great photo well done.
Tanju - My first instinct was to suggest cropping the photo tighter to the swan. But, the water and reflections are quite nice. Perhaps the empty space lower right could be cropped out though. Great exposure for the white of the swan. Thad
