What’s wrong with my mobility for snatches?

I did OLW for almost 2 years in the past but ended up taking a break due to a SLAP lesion on my left shoulder (it was not caused by OLW,it was a trauma from an accident while skating lul)

The healing process was a pain in the ass but i was able to get back and now i can do pretty much any exercise pain free and with lots of loads, including pull ups, chest dips, clean andsplit jerks.

But, it has been so hard to maintain a good position in the snatch. whenever i start overhead squating, it comes to a point where my torso will tilt forward and then, to compensate, my elbows will tilt backwards, and it gets super weird, i dont fell pain but i do feel a sort of discomfort on my left shoulder.

In the 2nd pic i did an OH Squat on top of the weight plates to get extra mobility and it felt super good, torso felt just right, and my shoulders felt awesome aswell.

I wish i was able to snatch the same as in the 2nd pic but without the plates, tho i dont know if im missing dorsiflexion, hip mobility or thoracic spine mobility, my clean feels fine, same as my back squats.

In also i little bit over my weight, maybe it is affecting my mobility?

Whats your thought?
