Just a brief update,
I got my second S.H. MonsterArts King Ghidorah. So far, I am having better luck with it than the first one I got. The joints are a lot more snug, and not falling off, and the wings are a-ok. I am not touching them excessively, and moving them only at the base.
As for my broken one, I am considering using to to make a diorama piece along with my second MonsterArts Godzilla figure for my school's art exhibit. However, let's see how things go first.
