Answer for How to correct my backspin serve

Thanks for the feedback guys.
I do understand that the first bounce cannot be too close to the net, but I seem to have difficulty controlling it to be closer to myself.
I will try with the bat being less flat, but I wanted it to be flat so that the serve can be short and that I can brush the ball more instead of more hitting.
I will experiment and see how it goes.
Cheers.
