This image definitely fits in the "artsy" category, which means that beauty is in the eye of the beholder. Some might say it lacks a well-defined subject, but to me, the subject is the track layout. It also has a nice sky going for it. But unfortunately, it's like something is missing and I can't quite put my finger on what. I want something more. Some rolling stock closer to the camera would have made it more interesting. I might also avoid cutting off that prominent switch stand in the foreground.....or crop it out entirely.
I keep coming back to "something is missing."
