The first two have too much out-of-focus stuff in the foreground and no clear area of interest. Moving in closer to part of the scene would have been better. The last one is interesting. This part of the building collapsed into an interesting pattern. Did you walk around and take this from different distances and angles? I have a feeling it might be worth showing more above where the frame ends, or moving in and getting part of the structure as more of an abstract pattern. As it is, I'd be tempted to crop the sides to remove most of the pieces of wood on the left and the empty space on the right. Looks like a place you could spend hours photographing, provided it's safe.
