Not bad. You hold your back in extension well. You occasionally drop your butt a little too low. Drop your butt when your bring your shins to the bar and drive your knees out instead of starting out too far in front of the bar and dropping your hips right before the pull. Narrow your stance 2 or 3 cm. See if you like how it feels. Lastly, keep your hands on the bar for all five reps.
