It was a competition or a friendly match?
Both of you seem really relaxed and not going for the match...
I don't really know how is working grade levels in USTA, but if you want to improve your game I can give you some tips
First, try to flex more your knees while serving, so you will get more power on your first serve.
Also, try to be a bit more agressive and attack the ball instead of move backwards while hitting the ball and finally, activate yourself during the rally. Try to be focus and ready all the time
Positive things is that you seem a natural for tennis. I really like your backhand
(really fluid movement) and your forehand is quite good as well
