The kong looked a little more like a speed vault, because you were running pretty fast there.
As far as your technique, I don't think you did a whole lot wrong.
Just watch some other people's vids and see how they're doing things, and if you can, throw your own little twist on shit, make it your signature style. A lot of PK vids look similar because not a lot of people have changed the moves to fit their own style, like people in rollerblading or snowboarding have.
But, eh, this is all just my opinion.
