There is very minimal leg drive. The feet are collapsing inward which is a tell tale sign. Try not flailing the toes so much. When you place the foot down drive your foot to the front of your shoe and drive your knees out. Try getting your hips off the bench before unracking the weight. If you can tuck your feet more or get them wider.
Lastly, tough to tell on the video but your upper body looks like it could be tighter. Take a second to settle the weight into your lats and push your belly up towards the bar
