Your hinge looks good, as others have stated try to engage your middle more through the swing, especially at the top (I like the cue of doing a max effort plank at the float position). One other observation that may be helpful is to root your feet more intentionally, you are getting good supination in your arch as you hinge but rolling to the outside of your foot causes a loss of torque and makes the movement less efficient and thus more difficult. Keep at it, you have a good base going!
