This has a great perspective, good composition and I very much like the subtle tones.

I like this photo, but it's too dark and so doesn't show much detail.

I think this needs more contrast for me. Is weathered and old the same?

Top marks from me on this image. I like your choice of low contrast and a dark, almost foreboding overall feel to the image. Stark and weathered.

I like the composition. Would like to see more contrast.

Although definitely weathered I'm finding it difficult to view, my eye doesn't know where to sit in this image. Also maybe a little dark.
