It's a decent deadlift, but I'd like to see you set your back harder. You're flexible enough to have a pretty flat back without really trying, but that doesn't mean you don't need to squeeze the shit out of those important muscles that help you maintain a flat back under load. Watch your last two reps. See the low back rounding? That's what happens if you don't set properly.
Before you pull each rep, take a deep breath and squeeze your chest up as hard as you can. Try to point your nipples at the wall. Then pull.
P.S. Side boob at :42. Thanks for that.
