What do I know, but your forearms are out (instead of vertical), and you start pretty leaned back, then don't get aggressively under the bar. I actually do touch my nose often going up and down, and really get under it the minute the bar passes my forehead.
Grip closer, and oh yeah, really try to almost sit the bar on your palms instead of grab it--the stronger your thumb grip the more the bar sits on your pinky.
