I'm not too wild about the postprocessing either, like Dmitry, but the storytelling is great; I like the angle of the kid, to me, it emphasises the dynamism, ready to take the leap.
I'm curious why you went for this approach, looking at your other photos, I think B&W would've been a better solution.
I like your photograph. Very interesting to look at. You captured all the motion of the youung person running along the top of the railcar at the right time.
Perfect story and excellent crop but postwork seems to be inaccurate. But thank you for the picture - if sky would not be so pink i could say this is masterpiece ;)
