Statue of the Unsung

[Nalien]

The horn shape is exactly the same, the only difference is the placement on primal Bahamut. They're at the side of his head rather than on top. Even the mouths are the same.

Let me just scribble on this;


The horn shape is different, and Bahamut doesn't have a beak. Meanwhile 4s wings match up to Bahamuts very nicely. Look at the top of 4s wings, and the top of Bahamuts wings, that claw like part is very similar on both.

The biggest issue with 4 is the angle... We're looking at his head from above, as such it's kind of hard to actually judge the horns adequately. We can tell that they're going back along the side of his head though, unlike 6, who has them curving over his face, which isn't at all how Bahamuts horns are depicted thus far.
