I never bought a Hero Factory set, so I cannot take that advice about bulking it up (plus, I think those pieces are a bit overused. But that's my opinion). And those parts on the side are not to add bulk... It actually helps with the structure of Quarix's torso.

As for King Vahi, I told my brother to make more original limbs, but that is one of his weaknesses when MOCing (at least I can do that). As for the helmut... It's suppost to be a crown... Yeah... It was not my idea. My brother likes to do crazy things with his MOCs, and one of them is experimenting with head designs, especially on Toa Metru heads.
