i'm pretty sure and really hoping that those are not gills at the base of his neck, just scales. the reason i hope that they are not is because that would really limit godzilla, in the old movies he could even survive in space( this is not unheard of in reality by the way, tiny creatures commonly known as water bears can survive in the vacum of space)! Godzilla has never had the biology of a normal animal. I know some would say that realism in the new movie would require something like gills, but i don'y thinck gareth wants to make the monster himself overly realistic, he is mainly going to make the human reaction/response realistic. In any case, realism would not allow godzilla to have gills, because he is a dinosaur, a reptile. to me, it looks like ovrelapping armor on his neck that makes it both tough and flexible, not gills . they look a bit thick for gills and we already know that this Godzilla will be heavily armored. as for the rest of the design, i love it, it has its own modern style, but it still is the old godzilla that we all know and love.
