a full face helmet and you'd have Darth Vader..,

actually that part was originally created for Mifune (Seven Samurai) and the costume designed for him with the samurai in mind, (just a point of interest if you are interested in these things; seems you are!) Mifune didn't take the part (after first being offered Obe One then later, Darth, because Lucas really wanted to help him break into Hollywood) because he thought Star Wars was a kids movie. Bad move!

the hiragana on the pieces of wood are their names.

texturing this one will be a challenge I would think??
