Hello Damon,
A very dramatic photo of an estuarine salt-marsh. It does evoke the lonely bleakness of these places - a bleakness that can also be beautiful at times. Maybe the sky is a bit too dramatic, as Asher suggests?
You mentioned the Napoleonic PoW hulks, so I wondered if it was the River Medway. I had this in mind, having been on a group tour of Chatham Historic Dockyard a couple of weeks ago. So I googled 'Horrid Hill' and sure enough it came up with a link to Gillingham, on the mouth of the Medway. There is another photo of the marsh, in misty weather, at:

So the location is in England. I don't think one ever gets English skies with such colour intensity. My wife came to look over my shoulder and immediately commented that if the clouds and sky were so contrasty, one would expect to see more evidence of it in the reflections on the water, even though the surface is not quite mirror-like. So that betrays the enchancement of the sky saturation. I think that you might have overdone that a bit.
With that reservation, I liked the lonely feel to this place. Only the modern buildings on the distant horizon remind one that it is only a few miles from London and its satellite towns. But then, I like photos without people in them - see my comments in the discussion of my recent submission to this forum at the end of June!
Best wishes. Martin.
