I really like the concept in this shot -- the RR tracks in the foreground with the plane in the background and the city in the middle. Nice idea. I'm envious!
If I could change some things: 1) the horizon is tilted down to the right; 2) the sky has a large bright spot in the top middle that looks unreal; 3) the RR tracks would be more interesting to me if the camera had been slightly higher above them. But these are just my thoughts. What matters most is what you think.
