looks good considering!
the main thing to work on, for you, at the moment, is the second pull ie explosively driving your hips forward into the bar (and making contact between the top third of the thigh and bar), elbows turned out/pronated throughout pull
reverse chain method might be worth a try ie start high and lower down on each rep until you are starting from the floor (1-2 from the top of the thigh, 1-2 from the knee and 1-2 from the floor, that's 1 set)
I suggest concentrating on perfect form with plenty of reps and sets for a lengthy period of time, don't worry about the weight for now, maybe just enough to have something to feel/work against
in terms of resources obviously there is stuff on this site but also greenwood weightlifting, sean waxman, catalyst athletics, iron mind, sportivny
