Not a premium member so I'm going to critique it here. Wonderfully clear with an almost painting like background. Visual movement throughout and some contrast between your bright and dark colors. visual movement in there but it took me awhile to find it. Rule of thirds used but in my opinion having the locomotive to the right a bit more would make it move better. Plus the orange on your lead locomotive looks a little washed out, not sure if it's a dirty locomotive or the image is a little over exposed. Otherwise nothing much wrong.
