Might not want to advertise it as RAW if you use straps.... you also don't need to use the alternate grip if using straps, just go double overhand and keep your biceps safe, or alternate and work your grip.
Either way, it's impressive how your head even goes back that far, but I don't see a problem with it. We are like horses, the body follows the head. I lead my deadlift off the floor with my head too, mine just doesn't go back as far.
More lat strength will help keep the bar in closer and let you keep your hips a little lower, but even as high as they are, your shoulders stay behind the bar so it's not too bad.
The only 2 things I could suggest... next time film the first rep, that's usually where a breakdown in form will happen.
and next time put some weight on the bar! That looked easy for you! It's easy to hold form carefully when the weight is only ~70-80% of your top end, a set at 90+ will show your weaknesses and areas for improvement a lot more.
Either way, you are stronger than this video shows.... and I completely agree with POB, either ditch the shoes or get some wrestling shoes. The heel throws you forward and robs pounds from your lift as it compresses.
