The lifts look pretty good from what I could see. One thing that I think could benefit you is bringing the bar back more off of the floor. So the bar is actually making an angle back towards your hips more in the 1st Pull. Your extension is great, but it looks like you may be initiating the 2nd Pull just a little bit too soon. Try to bring the bar up higher and more into the body before extending. I would suggest doing a complex of: Halting Snatch Deadlift
+ Snatch. Making sure you pause at the hip or the top of the thigh so you get the feeling of where the bar should be.
When receiving the bar, try to keep your head and chest up when turning the bar over. You're diving through and that is making the bar creep forward in the bottom position.
Try some light Dip Snatches and really focus on keeping the head and chest up more when turning the bar over.
