From the other video. While your backhand and serve look good your forehand finds you moving backward, mistiming, or maybe having to think too much. I would recommend a more conservative grip, that might help a bit. A similar forehand to yours to imitate might be Monfils with the more conservative grip but even Sinner, Fucsovics, or Casper Ruud have good forehands with much simpler take-backs for improved efficiency and results! 👍🏻
