Hi Harvey,
Interesting shot.
I know you were asking primarily about composition, and I will address that, but the first thing that hit my eye was the very bright water in the foreground. To me, it somewhat overwhelms the image, detracting from the interesting water, rocks, reflections, highlights in the background.
In terms of composition, things just seem a little out of balance. The shot is taken from a fairly high distance off the water (over which you not have had any choice), which tends to be a negative with shots involving wildlife (where you want to be reasonably close to eye level).
I really like the 'wake' left by the first goose, with the second goose, along with its wake, following from the left.
So I copied it into Photoshop and played around with it. The first thing I did was use the Shadows/Highlights tool to tone down the water in the foreground, and then cropped a fair amount from the bottom, and just a little on the top. Here is the result. Your thoughts?
