Good eye on the Grevious cloak. I had to trim it down a bit to make it work. I'm going to be making another version of this character soon taking aesevens advice and yours about the softgoods into account since this one is up on auction.
I love it! That's a great use of lots of cheap bootleg-type parts. You should make it a card and call the series 'Galaxy Wars' with a picture of the droid standing next to a upright calculator. Put the card on cardboard paper with no back side.
