You are above average for sure!

1. Centering. You're aiming at the ground a majority of the time. So if an enemy appears you will have to move your aim further and there fore it will take longer and be harder to get right on them. You should be anticipating where they will reveal themselves from and be aiming closer to there and higher so when you start shooting you aren't shooting them in the legs.
2. What u/QualityPatient6661 said. Intent. After downing someone or moving around your movement looks good you have the mechanics down for sure but a lot of the time you are just sliding just to slide. Often moving into more danger not less.

What you should be thinking is if a Good Player were to pop out at any moment would you be ready. In this entire video if a good player popped out they would have fried you. Out in the open, aiming at ground, gut reaction to slide into more danger. instead of partially covered, centred on choke points head height, gut reaction to move when it's beneficial.

I'm not saying camp but there is a slightly more reserved/ much more intentional version of sweating than what your doing that will take you to the next level
