You shouldn't lose points based on bottle appearance or fill level. That being said, you're paying $14 an entry for the NHC - if you're worried about DQ'ing then maybe should use the standard 12 oz bottle? I've ever seen one entry in a competition be nearly DQ'ed for a bottle, and that was an entry at the NC State fair where the brewer submitted a Heineken bottle with the Heineken label still in place. It was a stout, and you could clearly tell that it wasn't Heineken, but the judges were very close to DQ'ing it.
