Hi Deep,
Yeah looking forward to the ping pong, always good fun to watch. To be honest there you’ve listed all the key points and actually mentioned the main one which is the pinch on the bat and also fast acceleration to generate more spin. Serve practice is something I’ve done a lot in the past and it’s really helped me, I think players don’t often do enough an it’s a huge part of the game.
Also maybe height over the net is one thing you mentioned above, if you get a lot of spin and but the ball is too bouncy over the net a good opponent will still be able to flick or attack the serve. So keeping the ball tight to the net with a low contact point is also important.
But overall if you are serving regularly with those things in mind you will definitely see a difference in matches!
