Looking for a review of this game (5k vs 8k)

So i played this game against an ≈ 8k player. I ended up winning by a few points. My problem is that i have trouble spotting my big mistakes in this game so i figured i would ask you guys to find them for me :slight_smile: (I probably lost quite a few points in endgame though)

Edit : I am also looking for more general comments on how i could improve my game as i feel this kind of reflects my current level.
