With the video zoomed in it seems to hide your cut, but I would say that you're not cutting hard enough through the wake. Like 1boarder said, you should be screaming toward the wake. People in the boat always laugh at how when I cut it makes them feel like I'm pulling the boat over.
For the rotation - you're looking at your armpit. That's pretty close to what you'll do when you try an S-Bend. Like you've heard a million times already, look down the handle at the tower.
Your feet seem to be going behind you slightly slow. The trick should crack your back basically, and for me it feels like it doesn't really require much effort to bring it back in - when I was learning it and I was forcing my feet behind me it felt like I was pulling a freight train back under me. It should almost kind of snap your back and assist your feet back under you. If you hold your cut to the top of the wake and pop with the cut still held, you'll be popping your feet diagonally, throwing them behind you. When I pop like this I let my upper body pretty much go limp so I get horizontal.
If your not going balls to the wall you won't land it. Put some hot chics in the boat.
