I finished these about a week ago, both are based on the animated designs.
Has Lewa's mask because old Wariuha had it. It's supposed to have Kopaka's lower legs, but I didn't draw them quite right.
Has Tahu's mask because the old Akamai had it as well. It's kinda hard to NOT use Onua's traits more, especially being more noticeable than other parts. I kinda screwed up on the head and shoulders. Since Onua's more noticeable, let me point out the chest plate is Tahu's, upper arms and legs are Pohatu's. All hands are Gali hands, cause they're the easiest to draw.
So that's my interpretation of G2 Kaita models if they become a thing.
