Depth is much better. You have fixed that
You need to shove your knees out HARD at the bottom. They want to come in on you on the way out of the hole.
You're still lifting your chest a little early. Shove your hips straight up once you're at the bottom.
Look at the second set and see what your knees are doing at the bottom of rep 1, then compare that to rep 5.
Rep 1 is good; but your knees come abruptly forward when you get to the bottom of rep five. You can see this gradual breakdown over the course of the set. You are relaxing a little at the bottom. You need to stay tight the whole time.
