i don't know if you want feedback as you havent asked for it but here is my two cents, take it or leave it
#1. You need to utilise your L arm more effectively during the preparation of the stroke, ie pull back the racquet to force the R shoulder turn. It looks too passive
#2. bend at the knee not the waist, i see this a bit with 1hbh a little bit. Try to keep your back straight to maintain balance and posture and a vertical axis of rotation
#3. you need to work harder on your L leg movement to get it closer to the ball to allow a more linear path to your stroke, with momentum driving behind the racquet. The two best BH you hit in that vid had good L leg positioning as a foundation to the stroke (despite the fact that one of them was when you were pushed wide and had to hit a semi-open BH (nice shot too))
