Looks like good snow Bushwacker, no other people on that run? Nice!
Here's what I see. Fast/aggressive skiing, but you are using your strength and muscling your turns because you aren't getting enough shovel pressure. You're back on your tails a lot and you're pulling the tips around instead of riding them. This can be seen especially as you pull your left hand across your body in a left turn, your right hand is often back/down at your hip and your upper body/shoulders are twisting a lot because of this as you finish your turn.
You need to get forward, calm your arm/hand movements down, and focus on keeping your chest square to the fall line. All of these suggestions revolve around your pole plant which is your weak link IMO. The good news is this is a relatively quick and easy fix that will produce almost instant results/feedback as it will naturally align other pieces of the puzzle. It doesn't make any sense to work/focus on anything else until you dial in your pole plant. Your are carrying a lot of speed and this demands a crisp/clean pole plant.
CVJ and I have repeatedly commented on the importance of the pole plant, this is key and cannot be overlooked. You want to focus on keeping both elbows out from the chest and forward of your chest. This will get your hands reaching down the hill and allow you to make your pole plant near your tips as opposed to your bindings. This will naturally square your chest and get you off your tails as your will be able to generate more forward/shovel pressure earlier in your turn.
I'm not trying to be condescending and hope Lars doesn't think I'm being to harsh. I think improving your pole plant will take you furthest and the quickest.
