I'd say that your footwork and bottom position are pretty darn good. The bar is getting in front of you from the start, though. I would say to keep your set up pretty much where it is, but make sure that your weight is back on your heels by the time the bar is at or past your knees.
I'm not sure if this is causing your butt to rise too much, or if your butt rising is forcing the bar forward. Either way, keep your butt down a bit longer.
Finally, try to be a bit more patient with the second pull so that the bar makes contact a little higher on your thigh.
Even with all that, I think you have a very solid foundation to build on. Keep it up!
