I actually like that photo quite a bit. I'm a huge fan of really good landscape/environment shots. Rundown industrial areas are among my favorite.
The only thing against this photo is it's busy. The sign is so domainant it takes away from the water and the action there. If hung in a display this photo would be an excellent candidate for the centerpiece shot surrounded by a series of companion detail shots of certain aspects to expand on the scene.
I went down there just to get a few pictures of the bridge and to my surprise there was an oil catcher under it! whooohooo! two birds with one stone there!
Yeah, actually, it was supposed to, but the "Loop Current" is stalling I think and it's not really making it that far. I think Louisiana is taking the brunt of things
