video-analysis-of-my-match

Hi guys, 
I will start by introducing myself since it’s the first time I post here.
My name is Martin and I’m from Italy. I play table tennis for 4 years and since last year I decided to put short pimples on my backhand. After a year an a half of playing with short pimples (I tried several but i prefered more grippy short pips that felt more similar to inverted) I am now thinking of going back to inverted. What would you take in consideration when deciding wether to play with short pips or not?
I will leave you the link of the latest match I played, hoping you could help me to identify areas of my game that need improvements, and if you could give me some drills to do that would help me achieving it. Another thing I struggle with is keeping a lead, as you will see in the video where I was winning 2-0 but ended up losing the match 3-2
