In my not very expert opinion it looks as though you aren't getting full extension at the top of the second pull. Looking at your bar path the bump you get off the mid thigh is sending the bar quite a long way infront of you. In all your lifts, particularly the 70kg lift, this is causing you to jump forward by quite a few inches as you pull under the bar.
Other than that the lifts look pretty strong. Better than mine at least!
