Hips lower is pretty much all I have to say. Most people who pull with their hips that high start with them lower, but then their hips shoot up faster than their chest. But your start position is just with your hips high lol.... which could be a good thing! it might mean that your legs aren't weak or anything, you just need to utilize them better.
My advice would be to start with your shins maybe an inch and a half to 2 inches further from the bar, and push your shins forward to meet the bar at a more extreme angle. That will force you to get your hips down and use more quads to break the weight from the floor.
