The more I watch the footage, the more interesting it looks.
Firstly, it is definately a nice action. My worry is that the windball seems to float out of the hand.
The feet are in a good place, upper body follows a nice shape.
Again, the more I watch the more it comes down to dynamism (sp?)
Assuming you possess the basic athleticism to bowl quick (not trying to be funny, this is obviously the starting point) the idea is to add explosion into the action.
I would not change any part of the basic action. I dont really buy into certain bits written about changing the leap and bending the back more.
I would look to add the explosion by focusing on the run-up and the left side of the body.
Fast bowling does not depend on how quickly you force the right arm over, but the force, speed and aggression with which the left arm and left leg work. The right side follows what the left side does.
The left arm must come up with aggression, come down hard towards the offstump and be pulled fast into the hip. The right arm then follows through with seeingly very little effort. The left leg must also come down hard and the speed of the runup must continue through the crease.
As I said, I like the action, it just needs flavour added.
- Hit the crease at pace
- Force the arm up with aggression
- Bring it down towards offstump with pace
- Bring it through hard with the elbow into the hip. In other words the left arm does not flow from high to low in a fluid arc. It goes from high, to pulled in aggressively to the hip and then follows through.
- Bring the left leg down hard.
Its a simple thing about being a quickie. The more the left side of the body works the less the right has to do and the quicker you will bowl.

Following through after the arm was at the hip
Hope this all makes sense and helps a little. Its never really about changing the action but adding to it.
