I think the lighting looks pretty good. A few things that already have been mentioned that distract from the photo are the wispy trees and the large out-of-focus hill. I would knock the hill down a little bit. This way, your camera can get a little lower and look up slightly at the crossing. With no other large land forms visible, the camera currently looks as if it would be suspended 40 feet in the air. There is some texture visible in the backdrop, too. But pretty good atmosphere.
