I like the shack alot and the way you caught the breeze on the cattails.. Is this close enough that you could have another go at it? What settings did you use, what time of day was it, did you try different POV's?
The reasons I ask these questions is because with some small adjustments you might have a very nice photo on hand.
As it is though, I find the concrete wall and the chain-link fence distracting. If you could change slightly the DOF to blur the woods behind, remove the fence and wall in-camera, have the shadows of an earlier or later time of day. Hell, get down in the water and see if something is there.
There is a derelict pack house not too far from me that I must have taken 500 or shots of at different times of day and changing angles. Not in one visit though. I'd look at my results for the day and go back with a different plan. Finally got 2 or 3 that I'm happy with.
