And now for the conclusion!! Tinykin may be right.
Xylit the body language of my opponent who clearly wanted to do a fast serve and get back in to it.
Down 4-7 in game 3 and taking 7 straight points showed some steel.
Your return of serve on the BH side was pretty good in this match.
There were a few FH shots where you took an all arm stroke and missed because your feet did move to the ball. But overall, I would say you look pretty good in this match.
One thing I think you could do to help your level is your serves. It is very easy to see what is on all your serves.
On the BH serve, you should learn how to make a topspin serve by coming up from under the ball rather than going over the ball like in a BH topspin shot. That way it is a little harder to see if it is backspin or topspin on the serve and you also can get much better sidespin that way.
On your FH serves, you would do well to learn a traditional pendulum serve where you take the middle, ring and pinky fingers off the handle and use more wrist. The reason: you can make backspin, sidespin topspin and dead serves look much more close to the same. And then you will learn how to get your serves to give you returns that are a few centimeters higher for easier 3rd ball attacks. Understanding how to create those kinds of serves coming from under the ball will also help you improve your return of serve even more.
Just my thoughts on things that would take you a level or two higher without too much work.
