Your squats look pretty damn strong to me. Your stance is wider than the standard shoulder width recommendation, but it does not appear to be hurting you. You can play with it to see if narrower feels better, but there's not a compelling reason to change based on your video. There's not much to critique here.
In general, having your camera man stand at a 45 degree angle to you is a good compromise. It keeps the plates out of the way and we can see hips, knees, and back. Since he was standing up and seems tall, it is impossible to tell if you are going below parallel. I think you are hitting depth each time, but having him take a knee might help with that.
You are already farther along than a lot of people when they run out of gas in the novice stages. The answer is, it depends. Your squats looked really good. I have a feeling you have quite a few more linear jumps ahead of you. Well done.Any ideas on how much longer I can push this novice progression?
