Good Tutorial
I was not in love with the windows though, you should work on those because they clash with the city landscape making them really stick out which is not what you want to do in a movie. You should also try using some sort of saturation or brightness on the objects from the skatepark because they seem way to new in comparison to the trainstation darkness look. The tracks need to be one behind the other because the perspection point is thrown off because of it. Nice step by step though. Possibly add more than just a train station next time because that seemed like a landscape that is not commonly used. I know there were the ones at the begining but those were not step by step. Decent job over all though.
