I like it. It gives him a bit of a more natural feel. A lighter color underbelly makes sense on an amphibious creature.
LOL But since when does Godzilla actually make sense? I don't think Godzilla should be made to look realistic in such a scientific way. I think one of the worst things anyone could do with Godzilla is to over-analyze what makes him work and try to present him in as scientifically/biologically accurate a way as possible. Godzilla shouldn't look naural, because nothing about him is
natural. I guess we'll just wait and see what LP ends up doing.
I never quite understood the idea of "Well, since this is impossible, lets make it totally in left field" philosophy with design. Its part of the reason why I don't like half of the Tsuburaya Ultraman creations.
And if I wanted him to look completely natural, I'd suggest this:
But that's not what I suggested, is it?
I merely suggested that Godzilla have a natural coloration.
I'll just say it now: the idea that "Godzilla isn't natural, therefore, he should look as unnatural as possible" is a totally dipshit excuse. Its covering up a lack of creativity, a lack of critical thought, and/or a conservative mindset that hinders ideas. I've no qualms if you don't like the concept, but your reasoning is totally unfounded. Hell, Godzilla may not be natural, but doing things as unnatural as possible is just a bad idea. You have to create a believable narrative and sequence for a film. Therefore, in a Godzilla narrative, he should at least reflect some type natural law present in the narrative.
In fact, it has been done in the Godzilla films before. Heisei Godzilla's all-black coloration fits in for the swimming and deep sea reptile that he was. Its hard to see a black creature in the dark abyss.
