I personally really like the look of the overgrown railroad. The sides are slightly rusted over with some writing on the tracks. The orange flowers in the foreground of the image pair nicely with the rusty tinted tracks. There is also a dusty overlay on the image giving it a mid-western look.
For this image I was very conscious about the center point of my image, I had to make sure I knew where my lines would be meeting. The most noticeable lines come from the rusted train tracks. But the hills on either side of the image also lead towards the end of the tracks which adds to the photo.
