Note on the Jerk. It looks to me like your front knee in the split position is substantially further forward of your toes than I'm used to seeing. Look at pictures of world class lifters and you will usually see their front shin within 10-15 degrees of vertical, though so have the knee forward of a vertical shin and some have it behind vertical.
Also, from the starting position of the clean, you have a pretty upright torso and the fronts of your shoulders are about even with the bar, your scapulae behind the bar.
As you begin the first pull, your hips rise faster than your shoulder so that your torso becomes less upright until your scapulae are above the bar, the front of your shoulders in front of the bar.
Remember from Uncle Rip's book that from the floor the bar wants to be below the scaps. My coach is always yelling at me to keep my shoulder in front of the bar, which means the bar is under the scaps.
On your snatches, I think your first one, from the high hang, was the best. It looks to my relatively untrained eye like you're doing what I do from the floor versus the hang, which is to start accelerating the bar earlier than you should. It looks more pronounced from the floor than from below the knees.
Look at the third snatch, from the floor, versus the first two. The movement of the bar seems to have a little less velocity, a little less "snap" as a result from starting the acceleration earlier.
I might be completely wrong, but that's how it appears to me.
Nice work overall.
