This one is nice too, but I'd try a little perspective/skew work to straighten the rivet lines - not sure how this would work because it clearly wasn't shot straight-on so it might look a little strange.
When I looked at your picture, the contrasting colors of paint to rust set the tone for me. But it was that beam running through the picture that made me take a good long look. I quickly noticed that the vertical lines aren't vertical. Can this be corrected, or was this done intentionally?
Unfortunately, both are soft. They were from my early learning stages, and with soft kit lenses.
The other set doesn't look bad printed at a medium size, but my vision for that set is to be a huge wall piece.
It wasn't too long after that I got better lenses, and better understanding.
