Looks pretty solid. I'd start with lower hips and keep your chest up more, as soon as you break off teh floor your chest dips because your hips come up slightly too fast and it's hard to recovery from this position.
Hip and Shoulder angle should stay pretty rock solid at least up until mid thigh.
You crumple under the bar on your receive. When you get under drive your elbows up high. This will help your upperback be stronger on the receive.
Good work and keep on posting videos!
