This looks just a tad bit underexposed. I'd like to see it a little brighter to really bring out the white in the goose feathers - theyre a little too grey
I wish this weren't so much in shadow. I'd tighten up the drop and eliminate some of the negative space surrounding the geese as well. With better lighting, you could shoe off the details of their feathers and coloration better.
the waters here look "muddy" - try shooting scenes like this when the sun is casted across the water for a more dramatic effect. Remember - light and shadows are what we capture to make great shots - not just a worthy subject
