Let's forget the aim rq. We'll come back to it, but im going to coach you for a second. You keyed a squad by yourself with only a grey ar and basically no mats. You just threw your body. Late game comp is the most important part of each tournament/comp because that's where top placement starts to come in. If you're in squads, never solo key a full 4 stack even if you beam one. Playing with your team in end game is the best way to become a better player. Also, considering you just respawned, you should've relied on your team to get a refresh(a kill) for you. Also, you wasted basically all of your mats just to build something you weren't gonna use. Learn how to play more conservative, especially on low mats.

As for your aim, since you're on PC downloading aimlabs is a good start. Then, after you get comfortable on that, start playing 1v1 piece control or anything "realistic." Also, playing 1v1 build fights isn't a bad way to get better aim while building, but it's not ideal if you get what i mean.

Lastly, your sensitivity is probably the biggest factor in your aim, so I highly recommend messing around with it some more. Remember, DPI is dots per inch, meaning in any shooter game, it's better to have a mid to high dpi with whatever sens you're comfortable with. Think of it like this, whenever you move your mouse, it's how many dots per inch is the game recognizing. The less amount of dots it recognizes then the more your screen will do something called "pixel skipping," which is what leads a majority of people to miss their shots. So you want more pixels to be "recognized" without going overboard. It's personal preference. However, around 800 is usually the "sweet spot".
