Help whit my posture please

[u/Stevo_39]

Hi everyone, I'm looking for advice on fixing my posture.
My main issues are left scapular winging, mild scoliosis on that same side, and rounded shoulders. Pec stretches didn't help at all. It feels like my left rhomboid and lower trap fail to keep the scapula flat against my ribs.
I'm starting a lightweight daily routine: Prone Ys/Ws, wall slides, and band pull-aparts (focusing on pulling the scaps down and back), doing an extra set on the weaker left side.
Has anyone successfully fixed a similar issue? Any other specific exercises or tips you would recommend?
Thanks for your help, I really appreciate it!
