Help with Scapula Protraction, Weak Serratus/Trap?

Hello,

I believe I have a winged right scapula, in the first picture I am squeezing my blades together and you can notice the right blade “coming out” from the back. The second picture is the correct posture (I believe) that I can only keep trying to protracte the right scapula. My right trap is undeveloped/in the wrong position and I think a weak right serratus is the cause.
Has someone had the same problem? I’m actually training three times a week focusing on correcting my problem, trying to reinforce the serratus but I don’t feel it working. Do you have any advices? Thanks to who’s gonna answer.
