The 2nd one, I have no doubt he'll look scarier than that second pic could ever be in the actual film.
sorry, dont like the fan edited one, looks too cartoonish and well, this will sound redundant, but like how a typical fan wouldve made godzilla, and yes its beacuase it was made by a fan. He will probably look fiercer live action like how in the 2nd trailer he looked at hte end.
the edit looks like a vampiric Godzilla, so a "Dracuzilla!" Not crazy about it...
Lets stick to the original photo
While the fan edit is really cool and all, it feels a bit unnatural. And not in a good, Godzilla-unnatural way. So i would stick with the second, and original photo.
