Definitely the right direction. To start with though your right foot is too heel skywards/toe down/backwards...so as you are planting it down you hare having to rotate it. Instead it should be coming down slightly toe-heel and closed, so that you can shift into it rather than pre-spinning with it (you need all the force to come into it, not have it lead the throw). You are also landing on the front leg with it too straight, so to stay behind the brace you have to be angled well behind the foot. If your leg is slightly bend and ready to absorb and extend then you can stay balanced on top of the brace. Finally, your rear foot is acting as a counterbalance rather than shifting and then acting as a counterbalance, but I think this is because you are leading the rotation with the right foot/hip as I mentioned above. Again, this is the right direction from before, but still lots of little things that will greatly change how much momentum is moving into the brace. As far as upper body, you need to keep the reachback lower, like sternum height or around the rear elbow. With it getting up so high it's throwing off the swing plane and getting your shoulder out. Also looking at the camera doesn't help heh
