Keep the bar over mid-foot during your set-up. Meaning don't drop your hips and push it forward, and don't start with it forward. You made both of these errors throughout the set. Make sure the bar is over mid-foot and your own weight are balanced on your midfoot, then think about squeezing the bar up your legs, no yanking or jerking.
And don't breathe out at lockout! You may utilize your full share of the planet's oxygen supply when the bar is on the floor. Air is support, and you don't want to lose support for the spinal column at the top of the deadlift.
