Just a quick question and clarification on the bumps..
What was the intention of the bump run? Zipper line as fast as you can? or smoother rounder turns? you do mention absorbing.
RE your short turns, What skis are you on? (radius and model)
Lots of good stuff going on and a few hiccups as well. Intensity and max edge angles seems to be happening close to the fall line but then being hung onto well into the lower /exit of the turn. Reasonable separation of the upper and lower body. shoulders are relatively level and reasonable counter/anticipation at the end of your turns. Interesting that you are in Canada and yet you don't have quite as much of that "compact Canadian CSIA" look to your short turns.
I think the hands are more a symptom of other things going on under your feet. Almost like you are trying the make the hands fix some timing/edge release issues. I'd like to see more focus on tipping the inside ski and steering (not just pushing) both skis to an earlier edge. I'd also like to see you take those same size turns and really slow them down. Steered just a touch more throughout the whole turn without a push. A little more patience at the top of the turn allowing your COM to come over the skis and down the hill to affect a better more precise simultaneous edge release/change, and better edge engagement as you balance on the new outside ski.
