Normally I don't much like your stuff, Joe, but I quite like this.
I disagree with all the suggestions about crops and things, I think all the elements in place. If this were mine, I would file it away and go reshoot some more though, so I agree with jenko. There are some variations in the relationships between the forms that will evolve as the sun moves that I think could be interesting.
I like the sliver of tree trunk balanced against the sliver of chain-link fence. The electrical wires and so on root this in reality, make it a little on the "vernacular" side of things. The window, the door, and the shadow are the main players here, to my eye, and I think it would be interesting to see what happens with the shadow moved one way or the other. I might also move left or right to compress the existing frame into a format closer to square, and crop appropriately to retain the current relationships, but more horizontally compressed.
Not saying that I think any of these changes is definitely better. This is just the set of changes I would ring. Then, looking through the lot of them, one would certainly be better than the others -- and it might just be this one.
