Actually the pointy things are an element from traditional Samurai helmets, that the Gundam designers used. And the chest thing isn't a subwoofer, it's supposed to be a hole for some energy beam. I dunno, I stole the torso off an existing design.
Cool, looks all clean and sterile, like it belongs to the bad-guy-but-really-good-guy-deep-inside or something like that I like how you put the pilot in there, really puts the size of your gundam in perspective
