That's pretty good for 10 days.
It is pretty normal for an instructor to emphasize a quiet upper body when starting out. That's the point in the learning progression where you don't want all kinds of extra variables happening that will make it harder to learn and also the point where you need to ingrain good habits like body position, stance and balance.
Looks to me like you're pretty comfortable with those concepts and they seem pretty well-ingrained (ie you're not fighting to keep your balance, you're pretty centered, you're not counter-rotated and you look pretty comfortable doing what you're doing)
Time to start using the lower body to initiate the turns and generally become more dynamic.
My experience has been that when you get to the point that you're at now, the learning process accelerates and you almost feel like you're getting better every run instead of every day! Enjoy!
