This photo does not give me the impression that the camera was on or close to the ground. I know from some of my first photo attempts for this challenge that this can be misleading though. IMO the shot would have been better if the rooftops weren't visible.
I wish you had gotten a liitle lower to give a little different perspective, but you still achieved the goal of the challenge and you have a good exposure.
Wonderful textures, great sense of erosion and decay, set off by a dramatic sky :). I think though that either the cimneys (?) at the side or the electrical wiring would make a better subject on its own, rather than framing them both together.
I like the rustiness, as it contrasts very well with the blue sky. It seems like it maybe could have been better composed - there are a lot of places where lines are cut off, yet it doesn't completely fill the frame.
