Wow...That is the best of the best, right there.
After staring at that image for about 10 minutes, I've decided the biggest difference between Justin's Creep and other masks, even direct recasts of surviving 75 Shatners, is that the Creep has a weird sort of soul...It's accurate to a 75, but it's also sculpted with some of the specific quirks and oddities of the real H1 mask in mind. That gives it a very undeniable edge that stands up to today's steepest competition.
Congratulations on a job well-done, man. You've created another monster!!
