My progress has been very good, in terms of improving my numbers, it's not the time for that right now, I've been really brining up my glutes and relearning my squat again so I don't squat so quad dominant, which has led to a ton of knee pain. I've ben doing a ton of split squats, lunges and step ups, and hip thrust variations. It's been going well and I'm just starting a 6 week peak to bring my squat back up to 500, then from there I'll decide How I want to progress to 550, then 600.
I was more than happy to help before, and I honestly don't see many technical problems with your squat, you're flowing well. But, and I can't sugar coat this, they look high. I'd bring them down a good 4' and get comfortable there. It sucks, it really does, i've had to do it multiple times. But it's a pride thing, men squat below parallel raw. Above parallel you're cheating, it's ok to do it if that's what you want, but be aware, and be aware the glory of your accomplishments will be tarnished.
You say as you get to parallel you really feel your hamstrings. How tight are you? have you been stretching? have you been doing the warm up I showed you? Did I show you that warm up?
I just want to make sure you know your progress is extremely impressive, I hope you have your sights set on 405 and eventually 500.
How are you training right now? Program wise? what have you been using?
