Description of the match / things you want reviewed:
After attempting to VOD review myself I realised I don't really know if what I'm doing is the correct action. So I was hoping to see if someone else could point out my flaws, specifically on Sigma. Is there anything I could've done, with the knowledge I had, to prevent certain outcomes? Was my positioning what resulted in us losing fights? What should I do against a Zarya?

Got placed high Gold but have had a massive loss streak the past couple of days and wondering what I can change in my playstyle to stop myself from falling further, and potentially climbing back up.

Hello I did a video review to break down the positioning. On Sigma you didn't use as much range and power positions as you could have, and on Winston you played like Reinhardt, rarely taking advantage of the buildings on Paraiso to surround or stay above the other team. You also weren't going in deep with your Sombra against their backline, and used bubble in situations where it wasn't needed so it wasn't available for offense. I also didn't mention it in the video, but you seemed to willfully charge Zarya on point B, then the 1 really good play you made of primaling their Solider and Lifeweaver the fully charged Zarya also got 2.
