GMs should be renamed "ass poses" because of that vid!
You'r oly lifting has improved a lot! It doesn't look as awkward in the pull as it used to, no doubt because of practice! The snatch looks good, a bit of unbalance in the catch, but that's also something you just need to practice on. Good thing your mobility is good enough that you can sit pretty upright in the bottom of a squat.. I was never able to do that, so I never really learned how to snatch.
Also, don't be afraid to sit in the hole for a while after you have caught the bar.. if you start to raise too soon, while you're still unbalanced, you'll lose it.
It's the catch that you need to work the most on. Have you tried stuff like "snatch balances"
as for the set up. I think you could do with arching your back a bit more and staying tighter
