This works for motion and almost as an abstract (but I'm not really sure what you could have done to make it better without advanced editing) - the composition is great!
Abstract motion ok, but it doesn't really say WOW to me. Color is a bit flat, maybe you should have played a little with curves. Try it, it might surprise you.
Nicely abstracted. The train begins to appear less than solid. I wish the little beige triangle in the lower right corner could have been eliminated (slight shift of camera position, crop, or ... , realizing you can't clone in basic rules).
At first I thought, "just a nice motion shot, not that abstract." But I changed my mind the more I looked at it. Definitely abstract enough, I think it would be stronger saturated more to bring out the wonderful lines. they're very interesting, but your eye is drawn to the yellow more.
