Im a brown belt i keep missing kicks i need a tutorial to make a cool kick tell me a tut please.

Umm....
I don't see what your precisely asking for here.

Since you said you keep missing kicks maybe you should use your glutes, chest or lumbar. Those help alot when you try to aim moves.

extend both gluts contrac right hip extend left hip rotate chest right contact left pecs contrac right knee and space (10 framse) contrac right knee

Fixed.

Contract? Maybe you want to say "extend"...

And most important thing to do at beginning: hold all joints (c key)

If by contract all you mean hold all, then not always.
While you can create good openers by holding all, limp openers work just as good as hold all openers in most situations, if not better.

Here's a good opener kick...relax style!
