Travis, these don't show glaring issues to me, but there are a few things you can look into. I'll list them in the order of importance, but remember, I'm just the same random internet guy who reviewed your deadlift video a few minutes ago.
1. I think your chest/upper back is collapsing. Keeping a big, superman chest should tighten the whole back up pretty good. Just make sure not to confuse this with standing more upright.
2. You might try to narrow your grip a little.
3. Your wrists might be a little overextended.
4. It's hard to see the bar position, but I'll assume it's good.
