The colours from SMASH 3 seems a bit greenish and has a lighter colours in general
Godzilla from the first official trailer looks plain deep black with no shades of colours at all
Godzilla from Empire seems has orange and red shading all over his body
Godzilla from the toys promotional art and the brazil are have a different side-neck spike placing,but they're both has charcoal colours and no other shades of colours
The Neca figures,the Bandai figures,the jakks pacific toy all black and have a shade of brown on their chest and abdobment area..
The Godzilla encounter has a very strange head shape,has a gills,but the colous on his body is strikingly similar to the SMASH 3 godzilla and very similar to the last trailer..
encounter footage
SMASH 3
The jakks pacific toy
Neca toys
The Official trailer
The Official Teaser Trailer
Promotional Art
So what's goin on here? Overal they all have a similar design only have differences in colours,spike plating,gills positions,and posture..I assume the godzilla encounter and the main trailer are the final design,and the empire magazine's godzilal a bit over saturate..but that's just my guess..anyone have an idea ??
