The guardrail or whatever it is keeps me out of the shot. The most interesting part to me is the guardrail and the grass just beyond it. Like the S but nothing holds my interest out there.

I'm not sure what the horizontal metal-looking thing is at the bottom. At first I wasn't really sure why it was there but after spending a moment or two looking at your shot, I see that it does server to anchor the image and acts as a "start" for your curve. Nicely done.
I never in my life would have considered a marsh to be an interesting subject but you managed to do it--AND to make it look calm and in it's own way beautiful.
Lovely scenery, very interesting. It is a bit tilted, you can easily fix that. The railing (I think it's a railing) at the front really doesn't do anything for the photo, though, shooting beyond that or cropping it out would really improve this photo.
