Interesting... I like the train engine motiff of the Tinman's design, as well as the Greco-Roman adventuress costume of Dorothy -- ruby slippers/silver shoes as Mercury's sandals is certainly different.
Two questions: what was your thought pattern re: Scarecrow's redesign, and what does WOOZ stand for?
For the Scarecrow, I was going for a sophisticated butler motif, but I may have gotten a little carried away with the hay/facial hair look. I wanted to make him look just a bit intimidating, yet refined. "WOOZ" is just "Wizard of OZ", but employing the whole word OZ instead of just the "O". Thinking back on it, "WoOZ" might have made it a bit clearer.
Scarecrow-as-butler sounds interesting. Recently found out online that Jon Pertwee, one of the actors who played DR. WHO, later did a TV adaptation of some old English children's story series about a living scarecrow. Gives one an intresting idea -- the one who wants a brain as a brilliant-but-befuddled absent-minded professor type, eh?
