This image represents some changes that were suggested by members of the DP retouchers forum:
The train was rotated counter clockwise slightly, trying to follow the angle of the tracks.
Deciding to retain the lights, I darked the sky and added the orange tint to attempt a more realistic early morning sky. The lights in the building and on the signal tower were added.
Finally, added matte and frame to simulate the appearance that it will have hanging on the wall at work.
