Not too bad!
Three things to adjust. 1) Lower the hooks one notch. They are too high and when the weight gets heavy, re-racking will be horrific. 2) Your knees are getting too far forward and they are moving forward too late. Use a tubow to get used to stopping your knees just a hair in front of your toes and make sure they are done movimg forward by the time you're halfway down. 3) Don't let your head move around. You're head banging as you get tired near the end.
