Shove your knees out into your elbows and make room for your midsection to get between your thighs, so you can get your back flatter. Get your belt a little higher in the front and it will help you get your back set, as well. I think you've over-corrected on the distance from your shins. Get the barbell slightly back, directly over midfoot. You'll also need to get your weight centered over midfoot. Your weight is on your toes. Then, get your back set very hard. Bend the barbell up before you pull the deadlift, by means of getting your chest up hard.
Summary: your back isn't getting set well enough. Knees out, belt a little higher in the front, chest up so hard it bends the barbell.
