Wow. Nice, but laytex is a unholy bitch to work with. I had a guy try to make a mask for a TV pilot years ago, this guy was a experienced prop guy too, the whole thing fell apart.
I'd say follow instructions & good luck.
FYI being a Godzilla fan I do know a lot about laytex suits. They tend to dry out over time & crumble. That's why there aren't any old Godzilla suits (Shodai-Gogi, Kin-Gogi etc.) in museums in Japan. just replicas.
