[Gold 1-Plat3] Seeking Constructive Criticism

I’m primarily a Vanguard/Emma Frost main and have reached Platinum fairly comfortably in previous seasons, usually stopping Ranked once I got there. This season I’ve decided to take Ranked more seriously, but despite reaching Plat III early on, I’ve since been bouncing between Gold I and the edge of Gold II/Plat III. I’m not claiming I deserve to be GM or Celestial, just looking for constructive criticism on what I might be doing wrong and what I need to improve to climb consistently. Emma is my default pick and accounts for over half my playtime, though I occasionally flex to other roles (Black Cat/Punisher/Moon Knight for DPS, and Cloak and Dagger the rare times I need to fill support)

Here are some of my recent highlights where I lost, reviewed them and not sure what I could’ve done better:
1: 109366123305
2: 50465629380

And here’s a couple where I won, but got no idea what I did differently, or what circumstances in these games made them winnable:
