Morning Rob. I think you've got more in you but we need to address some form issues. You are very upright and need to lean over more (can you see how your back angle never really changes?). Really think about pushing your hips back right from the start. This will probably require taking a bit of weight off the bar but just really focus on getting bent over more by pushing your hips back on your warm-up sets and see what you can do. I will also note that while the video is at a poor angle to tell for sure I'm guessing your stance is a little wide and your knees are caving inward. When you take your stance make sure your heels are about shoulder width and then turn your toes our 15-30 degrees. Best of luck!
