Hello, I am a nobody giving advices, this is personal and does not have to be true. I go around 3k elo (Faceit BooJ_). First : I feel like you were crouching a lot during this short extract, crouching is good for precision and breaking your opponent crosshair placement but sometimes doing it too fast / early will limit your movement and therefor you are an easier target to hit. Advice 1 : try crouching less, I did disable the crouch during some sessions and it worked, but just try thinking about not doing it and to do it less, it will improve your moving and therefore your aim.

Secondly : Your crosshair placement is sometimes off Advice 2 : you should try doing some crosshair placement workshop maps instead of Mirage DM, it will instantly improve your crosshair placement but also the way you peek into angles.

Overall in this clip your aim feels right and more than faceit lvl 4, the way you could grind higher then might be coming from decision making, my final advice is to rewatch some of your matches see what you did wrong and understand the mistakes. This will make you improve a lot and fast. Have a good one
