Squats Form Check

Been doing the Starting Strength program for a months now and making some good progress.
Goodlife Fitness at Coxwell is a really nice gym. Opened last summer so all the equipment is still relatively new and in good repair.
Monday to Friday it opens at 5:00 am and I'm usually in there for an hour some time between 6 and 7:30 am. and it's never crowded, there's rarely a time when you have to wait for a bench, and NO ONE ever uses the squat rack. A few brave souls dare the Smith machine, but the squat rack is always open.
