Yeah I do! Just I didn't travel along the railroad, it was a nearby lake. Great job with the color, and I like your choice to leave a large empty space in the foreground - it gives me the impression that the little boy has traveled a ways. This is one of my faves in this challenge.
Lovely idea, but for this to take me back, I think I'd need to see it from the child's point of view which is difficult from this overbearing vantage point. I'd have been tempted to get to his height or lower. The selective desaturation leaves me puzzled... I can't see what it's trying to achieve. I'd have prefered complete b&w. The composition is a little odd... are his feet in the centre of the frame because that's where you want my eye to focus first? I naturally want to look at his head first which is right at the top of the frame. IMO, the eye is more comfortable if the focal point is in the centre 3rd. 6
