Well technically this is an excellent shot despite a slight blowout of the whites in places. Love the dark bg which really makes the swan pop from the image. Personally for me it is cropped in too tight. These are such wild and elegant birds and should be given a bit more room to breath. Many people can take a technically good photo but more effort is needed with composition and it can make or break an image. Experiment more and have fun! A beautiful image, well done!
