i think the voyager costume is unsuccessful because you're trying an outfit that's too complex, and since kirby doesn't have shoulders or a neck it looks odd to just see half a body in black with a red stripe, a rank, and a communicator. you'd have been more successful with a vader model with a no-front helmet and black cape... your more successful models take advantage of the attributes kirby actually does have... a head for headwear, a waist for belts/pants, and arms/legs. technically it would look ok if kirby's arms were covered, but then the uniform would cover part of his face, which is why it doesn't work. it's almost like voyager PANTS.
