In the first pull, you should be driving downward through the rearfeet. You seem to be too far forward on your feet throughout the first and second pulls. And, you are shuffling forward at the catch, which is almost always a clue that the bar is too far in front.
Try not consciously thinking of driving through the toes or shrugging up at the top of the 2nd pull. Rather, hip extend, get your torso to vertical and hip flex quickly, getting down through flat feet again. You're wasting time going up when you could already be going down.
If you're in Ga., come see me down in Savannah some time. And, you should try a meet soon.
