First, read this:
Deadlift starting Position Critique
Then re-read the deadlift chapter from SS:BBT3.
You are not gripping the bar with straight legs and starting way way behind mid foot. The bar is easily several inches away from your (not) vertical shin. Thus, your shoulders are too far back.
Yes, your hips are too low, because your set up is wrong.
You are looking up. Are you looking in a mirror? Stop. Fixed gaze on a point 10-15 feet on the floor ahead of you. If you can't stop looking in the mirror, turn around and put your back toward it and face the inside of the gym.
You are not wearing shoes. Wear shoes. Why do people assume you have to deadlift in bare feet???
Are those regular, full-sized plates?
Work to do for sure. Follow-the deadlift set up procedure in Rip's post and in the book.
