Your wall jump in "unrealism" was really good, there was some other good flow in it. Try to keep your body vertically to get used to the fact you move up with your legs and use your arms to give you balance. A good sparrer / parkourer try to plan his movements. Of course, not 3-4 moves in advance, but when he starts a movement, he "knows where he is going". Try to cut your movements in different phases: run, landing on the feet to prepare a jump, jumping, landing, run again, etc. in your mind to make things more clear, that helps a lot.
Anyway, I am waiting for more ;)
