Arms should not be vertical anyway.. Those looked good to me man. That is as vertical a bar path as you can get, you set your back well, shoulders ahead of bar, hips high, and everything was tight. You may have lost your tightness on the last one or two but if that is heavy for you it wasn't a deal breaker. Hard to tell if your pulling the bar in to your shins at that angle, but consciously think about using your lats and pull the bar in to your shins and legs the whole way up. Keep being awesome.
