Now i love old run down buildings/structures but these pics seem a little bland which isnt helped by the lack of clouds in the sky.
In terms of composition the 1st isnt straight, naughty naughty

and they dont give any reference to what it is or how old it is, As they say a picture should speak a thousand words.
i would have got some nice grungy shots of the rust which has great orange tones in. A wide angle lens would have been great to shoot upwards giving a sense of height

cool find though
