Here is what I'm seeing at first glance
1) tighten your lower back as you get set, and keep it super tight throughout your lift. It looks like your back gets a bit soft as the weight breaks the ground.
2)you could be more patient (delay when you pull) and aggressive(pull like a squirrel invaded your nether regions) with your second pull.
3) on your jerk, punch under the bar more, once your elbows hit full extension, they should stay there, you are trying to extend and then catch the bar.
Keep it up!
