Keep an eye on the delts not starting too far forward on the pull. The bar may be just a tad bit too close. Pause the vid just before you pull and see if you see it on rep 1 and 4. Reps 2 and 3 look pretty good but stay tighter. You can see the delts start to shift forward a bit because the back wasn't locked in. It may help to get your hips down just a little more - it may be a bit too high of a starting position. Experiment a little w/ the hip position or the bar position and see if that helps. Changing on or the other slightly might help you get faster and more weight off the floor.
I see you reset on each pull which tells me you really wanna focus on each rep. That is a good thing. Looks pretty good overall to me. You have a pretty solid set up position on the initial part of the pull. Great camera angle too. Keep it up and good luck at your first meet.
