I find it difficult to really critique this skiing, because the skier is obviously making lazy turns on this easier terrain. Show us some footage on a bit steeper terrain where you have to turn out of the fall line just a little bit more, or where you are turning further across the fall line, even on this slope. Then we can find specifically what you might want to consider working on.
I see good fore-aft, you are moving forward during init of every turn in a diagonal movement. I see your edges being init'd before the apex.
Are you banking a bit here? yea ok. So what. On this terrain and at the speed you are skiing, it doesn't really matter. It would matter a lot more if you were going for big edge angles, turning further across the fall line while trying to still maintain your speed on this flat terrain, etc. With these lazier turns, I think its a bit of a moot point. You could work on your angulation in this scenario just to burn in the muscle memory, but honestly, its irrelevant for this turn shape, speed and terrain, it might even look contrived.
I agree that you should generally widen your stance a bit, get your feet more independent of each other, and just develop a bit more angulation here than you're doing now for the sake of consistency.
RR track turns on this terrain would be great for you to do, as someone already suggested. Try to ski down with zero skid. Focusing on tipping.
At higher speeds we can better evaluate whether you are balanced over your outside ski. I don't think it matters one single bit in this video.
