A few things you can correct immediately that would help. Narrow your stance so the heels are under the shoulders. Get your eyes on a spot on the floor about 3-4 feet out. Keep your chest pointed at the ground on the way up and drive your hips. Cut your depth off to right below parallel. Start with those.
You'll also need to fix the way you're holding the bar with your elbows cranked up. You're asking for some elbow pain down the road. I can't tell if the bar may be too high on your back or if you're upper back just isn't in extension. When you post a follow up form, shoot it from higher up and leave in the part where you get setup under the bar.
And get some lifting shoes.
