Composition is flawless, Frank. The blurred trees in the foreground really enhance the speed of the very well focused train. Added to my faves and nominated to the A.C.
This is an excellent action shot, like Rog has already said, the blur is in the right places, with the spot on clarity, and focus on the train is superb. Tigs♥ =^..^=
Um, hang on to those trees. They're really moving! I jest. But for an illustration of motion, I'd be perfectly ok with still trees, and a blurry train.
Also love the colors and the sky.
