Great idea and executed pretty good. Exposure is right on - and everything is in good focus. Compositionally, the triangle of background in the bottom right corner does not work. You may have had better luck if you placed the train more to the left to avoid the b/g showing (if possible.)
It's nice to see a photo that demonstrates so well the importance of background. I also wondered how much trouble it was to bring a model and find a train track. Good submission.
Very nice... the only thing I personally don't care for is the miniature tracks... maybe placing the train on the real rail and taking that shot would have been a little more effective. ... 6
