Solo tank stuck in silver

Hey all.

I solo q for tank as a Silver 3, and I'm not sure what to do in terms of improving and climbing rank. I typically play D.Va and Rein, but I try to play other tanks as well.

Here are some replays from my past three matches, let me know if there are things I need to improve from these!

H44B59 - Zarya, D.Va, Rein on Shambali

MQ62RJ - Zarya on Suravasa

BYF8M1- Orisa on Queen St.

And don't be afraid to rip into me, I need serious help lol.

Love,

Jenende
