JCR,
As mgilchest notes, your grip looks about 1" too wide on each hand. You want your forearms to be perpendicular to the floor.
You go through the steps to achieve a good grip with neutral wrists, but then let your wrists bend back. Keep them in a neutral, non-bent back position, with the bar directly over the bones of your forearms. The bar will probably not be racked on your shoulders, which is fine.
Shrug up harder at lockout. Really hard.
