Hey man, nice squats and cool rack. I've got a few things for you:
What I like:
no pelvic rounding - your pelvis doesn't round at all, and that's a very good thing, when the pelvis rounds the upper back has a tendancy to as well. you arch it nicely and keep it tight. Good job.
Execution - you have a solid controlled descent, and build a lot of tension before you go up, that's very important for max attempts.
torso position - i saw up above you were worried about bending forward, I wouldn't worry about this, you're very upright for a low bar position, and this is just what happens when you go low bar as you have to keep the bar inline with your feet or you'll be doing a good morning.
What I feel you can improve on:
bar grip - go thumbless on your bar grip, you'll find it much easier to get your shoulders underneath you while maintaining a tight upper back.
Depth/stance - you've got a depth issues, probably 3-4'...hold 4' up in front of you, it's not that much and not a big deal, you can get down there.
However, you're going to find it difficult as your feet are outside shoulder width and you have some fairly tight hips. I'll get to that. What tight hips mean is that you're going to find it hard to get down, it's like you hit a wall, plus a wider stance just puts more strain on the hips making this even harder.
So bring your feet in to shoulder width and give it a shot. You're going low bar, so don't sit back AS much, sit more in between your legs and let your knees go forward a bit more and you'll stay upright.
You may need to bring your bar up to medium bar height instead of low bar. This isn't a huge difference and will let you stay very upright.
If you make these changes and find getting out of the hole more difficult, don't freak out, you just need to bring your quads up a bit, do some front squats once a week, or more if you can, and you'll notice a big difference, as well they'll help you to build your new form.
HIPS: your hips are tight, from the back view I can see you wiggling and shifting slightly on your descent. Do this warm up before you squat, and you'll see a big reduction in your wiggling, as well as getting depth much easier.
That's about it I think, take all my advice with a grain of salt, as it's only 2 videos and I feel you're a good squatter
