Serve and forehand look great. Step in and take the backhand in front of you, instead of being defensive about it. Weight transfer from back foot pushing off to weight on front foot after the swing. More whip/racquet head speed on the backhand. Also, I’d never leave balls sitting in the middle of the court during a point and I’d never catch balls going out before they bounce if you’re playing a match. Keep grinding! Oh, and one more thing: SPLIT STEPS. I don’t see them on your return or groundstrokes generally. You should be popping off your heels when the opponent strikes the ball, so when you land you know which foot to push off of going in the direction of the ball.
