Yo bro- good job getting that up... I think you "power GM'd" it. I agree that once you get the form you will be able to handle more. Some thoughts, but ffknight hit on a lot of this:
1) What is behind you? Your back bend is pretty scary. I have been doing them long enough that I will go forward instead of back if I fall, it never hurts to have insurance. It is good to have someone around just in case while you are learning....
2)The reason I said no.1 is you are bending back to catch and pulling with your upperbody... Your hips should explode up/out and then drop under you... NEVER "pull" the bar back into you... very dangerous... you move around the bar which is moving up, not the other way around...
3)get your butt down, the proper curve in your lower back and the bar needs to move in closer to you... the bar is way out in front of you which probably is making the pull toward you more pronounced... you will probably jack up your shins pretty darn good liek everyone else does until you get your form down...
4) when you get it all together, the bar will move in a straight path, bottom to top... it is moving about a foot to a foot and a half back toward you...you should not need to move your feet... it will pull modestly slow for the first third, and almost instantly, (like the hang) for the top 2/3rds... the majority of the energy should come from your hips, not from and upper body pull, and when you pull, shrug, don't pull
Try practicing a lot with 135, get it down, and then move up slowly... I have no doubt you could handle a lot more...
here is a cool little vid-

she kind of exaggerates the drop, but it is textbook type form
also- great vids- I like that you take them from the side- much more useful than a front or 3/4 shot
