Here are some designs I did for Millennium fx a few months back. They were for the look of the Wooden King and Queen from the Doctor Who Christmas Special, The Doctor, the Widow and the Wardrobe. They evolved from something resembling a creepy Ent to something closer to a medieval relief sculpture or a chess piece.
The guys who built them did an amazing job of creating suits that had a cracked hard wooden texture but still allowed the actor to move about. Here's the finished King messing with the Doctor's sonic screwdriver.
