hmm i think you improved on flanking here a bit, u contested the right flank at the start of the game and even got to their backline once, but still stayed too much at the frontlines and on the robot, most of the time leave the robot to ur team, u can use that downtime between fights to set up for the next fight on flank
id say you sometimes panic during team fights, to help with that and to avoid panic, you should work on your positioning so you dont feel disoriented i find its the #1 way to feel in control of the environment and not panic ex. see your whole team, and see your enemies, without being in the middle of the whole fight happening, typically on a flank of some sort or even behind your team depending what the situation is (tbh i cant judge it properly which one to choose 100% of the time either)
u can improve on cover usage, as you climb higher, you will die more often if you stay in the open like this as the aim of your opponents will vastly improve
reaction times could be better, remember to get into the muscle memory of using your suzu for things like: seeing your teammate being pinned by enemy rein, predicting reaper ult, etc.
i think one mistake you still are doing in this vod is focusing a bit too much on your tank again ex. fight happening in the front, tank is way in the back, ur waiting for the tank to come back to heal his 70% hp, but the fight in the front has your squishies dying and your back is turned to them
