This image is cool, but I also think it falls a little flat, but not necessarily in a bad way. Almost feels like a drawing. Not a fan of the thick, white border, but that's a personal bias that I'm aware of.
From a technical standpoint, this is a terrific effort - crisp, sharp with everything detail well controlled and captured. From an artistic standpoint, it's rather bland and uninviting to the viewer - images occasionally suffer from too much detail and this is one. Sometimes an image, even one as technically competant as this one is, is just an image. A worthy entry into the challenge and directly related to the challenge subject. A good effort falling short in the artistic sense.
I came back to comment and bumped this one. The subtle, sharp detail and huge clouds of steam are wonderful on this shot. The viewer can almost hear the whistles and bells and clanks and creaks. This shouts.
