Not bad. Here's what needs fixing -
1. your weight shifts forward on your feet as the bar moves up your shins - you have a good start posiiton, b ut then you raise your hips faster than your shoulders and allow that to shift your weight to your toes. Stay back and keep your chest up.
2. Tied in with #1 is your extension - you do a back bridge. That works for super short weightlifters, but you don't qualify. Your body should essentially be straight, but inclined as a whole slightly backward. In other words, get your shoulders behind your hips, but dno't allow your hips to cross forward of the frontal plane as described by a vertical line through your shoulder, hip and ankle when standing straight. That means - Yes, weight will still be focused just in front of your heel even though you're extending on your toes.
