@ JUNKERDE - I am not aware of any newer, skinnier Godzilla. The Godzilla on the cover of Empire Magazine is the final version you know. Just look at the one in the trailer and compare it to the magazine. It's the same creature. Just a different angle. But that is the final Godzilla.
The "Concept Godzillas" have long since been revealed to be the Brazil shot, the 2012 teaser, the Godzilla encounter in 2013, the 2013 teaser shown in Hall H, and the teaser trailer we got before the official trailer release.
But the one on Empire Magazine is the final Godzilla. That's been confirmed.
Anyway, I like this Godzilla's face. I don't see anything rat-like about it. Gareth Edwards said they used dogs, bears, and eagles in the designing of Godzilla's face, so it's only natural that it's going to have a slightly mammalian feel to it at certain angles. If they modeled his face off of mammals, then it doesn't take a rocket scientist to know that he's going to have mammalian characteristics.
But yeah, the ultimate point is that I like it. I don't see anything weird about it or wrong with it. But that's just me.
