okay, lets give this puppy a try

The opening move is where someone has their hand on your shoulder from behind. This is a tricky school bully move to get you to turn when a sucker punch is waiting just behind the door. You trap your victim's hand on your shoulder, turn and hit colon 11-14. You roll your arm in a "snake kung-fu" move which indicates a potential arm bar, or a throw. The open hand strike goes to the 20 points of the neck. you know the next three moves really emphizes on neck and head strikes, so many meanings and stike points i can fill your box explaining them all. the main thing is while your guy is on his knees you are repeately hitting the neck and head. It looks like with the motion, the kata teaches mostly arm movement for slapping and jabbing.
while you are holding the arm that you trapped, you can step over the arm and body, hooking it into a break. rubbing colon 3-5 or putting pressure on the elbow tendons.
I also see a potential for throwing your victim into another attacker, and striking the mid section of the second attacker. the knuckle stike at mid section could be a set up for a kick which probally happens when you run out of film.
again, please slow yourself down and watch your posture. I see some sluching, and leaning. its a habit alot of americans have because of improper sitting habits at home. also when you step you have a tendency to raise your feet wich could be a balance issue. try to stay on the balls of your feet when you turn. watch your hip.
