I think bar closeness is going to be more about when you start to transition from first pull into getting underneath the bar. I don’t know what best practice is but I would say flaring your elbows out will end up loosening you up so I tend to point my elbows more inwards to keep tension in my shoulders etc.
If when you are pulling your are imagining hte bar just coming up vertically against your body then the idea to me seems to be in the perfect world the bar would keep floating up vertically as you get underneath it and let it drop down into front squat position. I think people can have a tendency to stop their pull too early so they’re kind of forcing the bar around which then will push it away from the body.
I don’t know if I’m explaining myself properly but it seems to me like your form is pretty bloody good and if you want to concentrate on anything to me it’d be your jump/land explosion between pull and getting under as you seem to be pulling the bar over that peak rather than getting underneath it and letting it drop. Also the pull you might want to concentrate on getting your elbows higher or basically extending the explosion of your pulling motion so that the bar does get high enough for you to get under.
That’s my two small tips.
