Dynamix,

I saw your video and here's what I have to say. I may note be a golf instructor but I do know what I see.

1. You're rushing your swing, especially your backswing. Go slower.
2. I immediately see head shift to left and reverse pivot on backswing which definately attributes to your loss of power.
3. In side view, your right leg got straight, loss of coiled power.
4. You are still very young, your muscles haven't developed and matured.

That's about all I can gather from the clip. If I can see your hands, then maybe I could give more feedback.
