I don't agree, I think that without the rail in the foreground the picture would lack interest. I like the colours and the idea behind the image. It may have been more powerful if the proportions were slightly different, with the beach occupying closer to 1/3 of the frame and the sea and sky 2/3. But it's a nice shot.
I like the rail in the picture. I would like to see it swing a little more into one mood or another. Like the same picture of the sky completely overcast, or of a sunny day.
