Well this is kind of a difficult coaching angle. Your technique looks pretty good all-around.
I would suggest getting your head up in the starting position. You bring it up after you start to lift it off of the ground but I would still go ahead and focus your vision straight ahead. On the miss it looks like you're "hanging" in the air a little bit before you pull under (comparing it to the first video). It's not excessive by any means, but when you're getting to max weights it will make or break a lift. Be careful though because you doing want to cut the 2nd Pull off short just to get under the bar. Just try to work on the quicker change of direction.
You can do some Block Snatches or even some little drills like Tall Snatches or Dip Snatches to isolate that portion of the movement.
Besides that point, it just looked like your elbows were a little soft in the bottom position. So you can always work that overhead position with some Snatch Push Presses or some Snatch Sots Presses.
