Only took a look at the 2nd set of squats, but i can tell you now that people on this forum won't be happy having to crane their head 90 degrees to watch it. This made depth pretty hard to judge, but i'd say with the way you sometimes had a fair bit of butt wink at the bottom means that you should be getting good depth. Try tightening up a bit more (if your getting ample depth maybe cut some depth to avoid too much butt wink.
And maybe try to get your wrists straightened out instead of bent under the bar as this could intercept some of the weight and lead to a case of bad elbow tendonitis (been there, done that)
Other than that well done
