Zxmbies: The rolls are pretty good overall, I just have a couple suggestions. There is really no point in putting your left leg out when you start your roll, because if you put your foot out before a roll while doing parkour, that defeats the purpose of a roll. They are meant to dissipate force, and once you take a step the force is all gone, so there is no benefit. Practice landing on two feet and then going into a roll, with no pause between landing and rolling(or only a very, very small pause...think milliseconds).
Someone else can read this and see if this suggestion is right, cause I don't really know from the video if this is what he is doing. It seems like, after you make first contact with your shoulder, you kind of land straight on the ground with your back, as opposed to rolling into it. This hurts your flow, and it is prolly more painful than normal rolls. So really try and imagine the roll where you never lose contact with the ground, but the contact you have is short and only one point of your body touches at one time. That sounds a little weird, but I'm basically saying have better flow.
