Parts usage is a win throughout -- the Bionicle helmet nose has been tried before, but nobody has ever thought of sticking guns through the eyes. The radial engines, built up out of the disc pieces, are my favorite part. Great job!
Original! Great use of Bionicle pieces! I don't think anybody's ever used that Vakama head as a nose for an airplane before. You always find such great and unusual ways to build LEGO and put something together.
