Not in any particular order (great music btw):
Your shoulders are hunched forward. Keep those shoulder blades tight.
Your hips seem way too high as well at the start, you are doing more of a powerlifting deadlift positional start. Get the hips down and flare the knees to the side.
Your hips are raising before the shoulders. It all needs to come up together - more than likely a product of the hips being too high.
