The horizon doesn't bother me too much as the fence poles give the truer indication. Maybe this would have worked better in portrait mode with a lot of the irrelevant stuff cropped out and the photo's leading line heading to the light rays.
the scene around when this picture was taken seems to be promising, but the picture as is lacks a focal point.
it appears that there are the beams from the clouds, which generally make for excellent pictures. perhaps you could have concentrated on that part for your picture. also, there are a large number of these posts in the background, and possibly they might have formed interesting lines had you chosen them for your subject.
as done, however, the subject appears to be the mud/sand in the foreground, which holds very little interest. also the line of poles cutting across don't contribute tha much.
I like the light from the sky and the repetation of the poles. Let's try to crop the below out and make the front pole as foreground. I am not a professional photographer, but let me know if it helps. And the horizon maybe a little tilted. Not sure if you intended or not. 7
if you're going to do a lot of burning, use your colour balance or a de-saturation tool when you're done to lose the blue cast. Burning on an adjustment layer is the easiest way to control it.
Aside from that, very nice pic. I'm sure a few will mention the slanter horizon, but i don't mind it...together with the posts it leads your eye nicely to the H2O.
