Squats are looking nice man just need an extra inch or two of depth but that is a massive improvement!
Try and control the negative a little more, that doesn't mean go slow it just means don't rush. On your last set you weren't bringing your glutes in enough but that is easy to correct.
Also you may want to think about sitting back a little more to get a little more posterior chain involvement but that isn't a huge deal.
Sorry just realised I may have been a little negative. It wasn't meant at all you have made huge progress there and I'm looking forward to seeing your deadlifts
