29% Soj win rate after nearly 70 QP games

So as the title says I’m absolutely abysmal with Sojourn, almost 10 hours and 70 matches in QP I’m embarrassingly at 20-48 for a 29% win rate. I’m a Masters Genji/Echo/Soldier player and wanted to pick up Soj so started practicing in QP, I’m not improving at all and I don’t know why.

Sometimes I do have a match where I feel like I’m playing decent and I favour us to win but then I can never close these games out?! They somehow always result in a loss regardless of if I think I had a decent game or not so clearly I’m not playing as well as I think at times. If it’s just that my aim is too ass for Soj then I’ll accept it and drop her.

Granted these are QP codes (if I take her into comp in masters I will never forgive myself lmao) but if anybody could have a look and let me know if there are some big flaws in how I’m playing Soj I would very much appreciate it. I’m close to giving up with her and moving on but I have a weird stubbornness about this - probably because I’m so bad with her and can’t accept it lol

Codes:
Rialto - EBPY4F
King’s Row - 8SNT75
Havana - 0SM8YJ
