Your stave doesn't appear very wide to me at all. Def Low Bar and good positioning on the bar. Might wanna play with it so you can find a better position that allows you to stay up tall a little more st the beginning. Where you are now will eventually cause you to fold over as the weight gets stronger. As for foot placement you don't appear to be very wide at all. I only say something because you specifically mentioned LBBS Wide Stance. Also you appear to still be trying to squat with your high bar tech which is causing alot of forward knee movement which with a wide stance lbbs you kinda want to eliminate that. The whole point is to load the posterior chain as best as you can. The more forward knee movement the less you can do that and you continue to count on the rebound. You need to shit back and then down externally rotating the hips out ward (screw the floor and push knee outs) while sitting back and down. This will effectively allow you to load the posterior chain and fire ot of the hole. On the leaning forward your going to have to dl that in low bar the amount is completely different for each person. The important thing is to keep elbows pulled down and under, upper back stays tight and nuetral and bar path is relatively up and down and just over or behind mid foot. If you get forward with the amount of forward lean you have you will dump the bar over your head as the weight begins to climb. Lastly reset and take a second between reps. Stop thinking about a set of 5 as 5 reps but rather 5 individual singles.
