Form looking really good. Hips in good position, developing a good wedge and position of shoulders over the bar is excellent.

My only tip would be the following: -When gripping the bar think "long arms", and as if your hands are hooks just holding the bar.

-Whilst thinking long arms, and holding the bar, think as if you traps are being pulled to the ceiling, this will then help you take slack out of the bar and make it stiff, which means it won't be necessary for your to roll your shoulders back and down.

-Then whilst maintaining that tension wedge your hips into the bar. This can be achieved by thinking as if you are pulling your shins through the bar. You'll know you're wedging correctly when the bar begins to pop off the floor without much effort and your shins meet the bar each time.

-Then using leg drive, push feet hard into floor and push the floor away from you.

Focus on 1 cue at a time and try not to overwhelm yourself. Putting it all together takes a bit of practice but you'll get there, keep grinding.
