One good thing i see right off the bat is a pretty good neutral back through the whole movement. No but tuck. You were looking down a few times which is a nono. Look straight or a little up, pick a spot to stare at and don't let your eyes leave that spot. Your knees shoot forward a bit but it's not terrible. Try and play with a little wider stance, torque those knees outward and split the earth. Also a box will really help with keeping the knees back and engaging that ass and those hammy's out of the bottom.
