I like this one a lot. The huge group of the white geese seems to merge with the complimentary, drak gry and white BG adding a lot of confusion to the image and that is what I like in this photograph: it seems like a snow texture and you have to watch carefully to realise that there are a lot of geese on the image. Ooops, I am not english fluent but I am sure that you know what I am talking about;)
