Hi Walter,
How was the raft of pelicans captured? Was it film or digital and is this orignally a jpg or a RAW file?
I ask since I have been looking at this for some while and wondering whether the one bird in the foreground with spread wings might be set apart from the others as the main focus of the image. but perhaps that goes against your idea of the unity of one raft of pelicans. I was exploring this change in composition since I feel that we need more width perhaps for this particular composition you have chosen to work at its best. That's just my thought.
Also, there seems to be a lot more detail possible in the hills in below the skyline.
In any case this is fascinating. I have never seen so many pelicans on the water, although I have seen them line up on woodern wharf structures.
At sunset that is striking!
