Hello Mocucha,
Thank you so much for putting this tutorial up. I have been practicing parkour for about 2 solid weeks and your video has been invaluable! In fact; I would have quit a long time ago if not for this video.
I practice on houseparkour a couple hours a day and have managed to take about 6 pretty wobbly steps and jump over the first wall; most of it accidental but its progress :-p I plan on posting replays to show my improvements once I figure out replays and the forums.
