How to escape bronze?

I’ve been stuck in bronze one for a while, I cant seem to get out. I mainly play tank (Peni and Strange), and Im wondering if there is something crucial Im missing or for lack of a better term, I just need to get good. I play on ps5 if that matters.

My name in game is: Excalibrrrr
