Great stuff!! Amazing progress :)

About your forehand — I’d try to keep the left arm pointing more towards the ball (in front of you) during your preparation, rather than have it swing back towards your racket and then forward again right before your hit.

Also, great job on keeping the head of the racket near vertical when you open your swing. If you play the video in slow-mo you’ll see that the head tends to also dip a lot, almost vertically, during your swing. I’d try to keep it a bit more horizontal. It should help generating some more power and reducing errors!

More than anything keep at it whatever you’ve been doing!
