This is a big improvement over your last videos. I would like to get your shoulders just very slightly farther forward right from the start - maybe an inch.
On your pull under, keep that bar back closer to you. This will get you under faster as well as keeping your balance and foot placement better. Speaking of that, stomp your feet down flat and aggressively - you don't need to pick them up higher really, but don't let them just sweep back on their own - straight up and straight down, re-establish a strong base right away.
First of all, you're a natural jerker - that's a hell of a good jerk. Get a bit more strength/stability in the trunk and upper back and elbows and you will be invincible.
The clean, same deal w the feet you have going on in the snatch - get them flat and under you right away. You crumbled on the first one because your feet were behind you.
Shoulders a bit more forward right from the start and stay over the bar longer - try to keep your shoulders in front of the bar until the bar is at least to mid-thigh. That will make your balance better and let you be quicker at the top and changing directions.
Finally, your arms are a bit stiff when you finish your extension - try to relax them a bit, and then engage to pull down slightly sooner. Push the bar in w your lats actively the whole time you're extending and as you pull under - you're letting the bar drift away from you a bit. Push in, elbows out, shoulders up into the bar, and you'll be balanced and solid in the squat.
