I'd suggest developing these skills with a detuned SL ski and once mastered transfered to the race stock GS ski. A race stock GS ski doesn't come alive until you hit 40+ MPH. A detuned SL ski can crank awesome turns at half that speed.

x2 knowing that you like skiing bumps and trees learning to ski a SL skis is much more beneficial than learning to ski a GS ski.

with that said I see alot of good. Pretty good uper and lower body separation, nice turn shape once on edge, generally good tipping. Stance might be a little narrow but as long as both feet move not as one its all good.   the video might be to low of quality but I suspect your pushing you feet out alittle to get to an edge instead of cleanly rolling from edge to edge while your COM moves in away to be balanced on your new outside ski. You need to learn to move with your skis on this phase of the turn and be patient enough so they can hook up.

I have been posting this video alot but its a is a great way to learn how to cleanly balance on your outside ski from the start of the turn....and its also teaches you how far and how fast you can tip with out losing balance on it.
