There is not much wrong with the turns in the brushed video except it’s not PMTS skiing
I'd just like to address this, as I've seen it said several times on the forum. At what point in a skiers progression is it considered "PMTS skiing"? I fully understand this comment for someone that has not really started to integrate PMTS movements into their skiing, but for anyone who has spent a lot of time working through the books and doing drills specific to PMTS movements, this statement seems unfair. Do we all have to ski like HH for it to be considered PMTS skiing?
As for the actual MA, I don't necessarily see a big heel push in the high c, it's hard to tell from this far at this speed whether the pivot comes from tipping and CA or an active push or twist. What I do see is a lack of edge engagement in the high c. Which causes you to get your speed control only in the second half of the turn. It seems like due to the greater forces in turns like these you are not getting your weight transferred to your LTE prior to transition, and maintaining that balance through the top of the next arc. Greater flexion of the old stance ski might be helpful so you don't get catapulted up and away from the snow. I would slow down and practice some garlands or super phantom on a slope like that to practice that weight transfer.
