Some points to ponder.
First, I agree with TheRusty on the rhythm and flow of the turns - nice.
Other than a couple of times, I thought you did a pretty good job of keeping your shoulders level.
In fact, if you asked me what I thought you were focusing on for that run,
I would say it was trying to keep your shoulders level and facing them square down the fall line.
As TheRusty points out, I would like to see your feet under you a bit more with ankle flex and more vertical femurs.
This enables you to better pressure and engage the fronts of the skis into and throughout the turn.
It also looked like you were skiing smoother and better well before you got to the camera but it was hard to see that far away.
At some point it looked like you began to make shorter radius turns as you approached and continued those on down.
What I saw was while the shoulders were constantly facing downhill, the hips were not. They were moving with the legs and skis.
It looked like you were winding up the spring between your shoulders and your hips and then using that tension to unwind your skis into a turn.
This is particularly noticable at 18 secs into the vid.
This results in your hips not being countered into the turn (like your shoulders are) and blocks your ability to angulate at the hips and
thereby get more edge angle into and throughout the turn.
I kinda also got the feeling you were making individual turns. OK, that one is done, now for the next one kinda thing.
This is where the first 4-5 turns in the video looked to have alot smoother transition and flow between turns.
1. Get your feet under you more to pressure the front of your skis more to be able to engage the front edges more.
2. Wrap your poles around your hips (the Hip-O-Meter) and try to keep them as level and facing downhill as you are with your shoulders.
(By the way, you don't need to keep them facing that much downhill all the time for those size turns. Nice drill though.)
This is classic independent leg rotation we are looking for here. The legs are turning more than the hips. The femurs are rotating
back and forth in a stable/quiet hip socket. We steer the feet not twist the torso.
3. Think about starting to let the old turn go about 3/4 of the way around the turn.
Begin to unedge the skis there to start releasing the edges and your CoM out of the old turn and moving into the new.
(BTW, I sometimes think that un-edging is almost more important than edging).
These open the door to higher, earlier edge engagement and carving.
