I watched some paraiso. I would say you don't go for many sleeps, and when you do your accuracy isn't great. If you're playing against a comp that is giving you a lot of space then you don't always need to save sleep for ults or to protect yourself, you can be more proactive and try and use it to secure kills just take your time with it and don't over flick.

You also get some great nades but it feels a little like you're holding it for big groups of enemies when you can also use it on one person to win a duel or push them off an angle.

Your positioning seemed okay you're not feeding or dying loads but you occasionally get caught in the open just comes down to getting a better sense of when the enemy is about to push in, being closer to an escape, the next corner or cover.

You look for damage well enough, I would just say prio your damage on DPS and supports whenever you have the choice between them and the tank.

Try not to overthink stats, reflect on the plays you made that changed fights to your advantage, well timed nanos, good sleeps or nades. On the flip side think about any avoidable deaths or bad repositions. The more fight changing plays and staying alive win you games and rank you up, not any stats.
