Deadlift form check

[weightliftingfan1]

I am wondering if it is a problem that my back angle is not constant while the bar is traveling from the floor to my knees.
My deadlift fits Rip's main criteria, but I am still a little concerned about my form. I am mainly wondering if anyone can see anything in this video that would explain my back angle (anthropometry, incorrect form, etc) changing too soon.
If it helps, my height is 6' 5.5''

Thanks for your help.

You are trying to stand up just a bit early. Think "push middle of foot into floor" when you start the movement. Other than that, this is fine.
