I don't know how to put this correctly, but what I love is that the whole image looks "layered". From bottom to top it just keeps changing. You have rippled water, mist, vegetation, and what appears to be about 5 or 6 bands of color in the sky. The image keeps drawing my eye back and forth over it.
Very evocative. I love the colors and composition. Paul said it well - the "layered look" makes the image. I don't mind the oof landscape, in fact I rather like it. I might have wished that the geese were a little sharper but you were working in very dim light conditions and forced to go with a relatively slow SS. Very nice.
Ben, this is really lovely but I do have a few suggestions for you.
First, I'd clone out the two birds that are below the others as they are nothing more than specs. It would be nice if the other birds had been more in focus but at least they are discernible whereas the other two really aren't adding anything to the image.
Also, the darker area of the sky appears to have some noise - I ran a quick NR round and it cleared it right up. You could also try lightening the sky a bit and that would help pull out the noise.
Finally, the tree line stops abruptly towards the right side of the frame. I realize this is where that part of the coast probably ends but it looks incomplete to me. I'd either clone the vegetation to the edge of the frame or I'd crop in a bit to exclude it from the image if it were mine.
Lovely oranges...it's my new favorite color! I never liked orange before but its quickly growing on me. That dark orange mist at the base of the vegetation is so intense and beautiful! Well seen and captured!
That is a really nice image! Great colors and composition, there is a bit of noise, but still great IQ for 1600 ISO. Jules has some good suggestions, but great capture.
