Either. Whicever era ya choose. I think pulling off the later years (ala Star, Nuremburg, etc.) would be harder. I would love to (someday) do an entire 3D model of all the characters and set of Judgement and Nuremburg. Ha! It'd put Ted Turner and his damn finger paints out of business! But whichever era you choose. As for the Oz one, I've spent a year on a pair of Ruby Slippers. I thought it'd be easy, but I'm designing them based on the Christie Auction Diagram I have a copy of - so 2,500 a shoe has proven to be a nightmare :) But the challenge - it's up to you. I don't care what era or decade. The challenge is to make a 3D model. To me she is one of the more underappreciated performers - I mean, I've seen 3D Elvis's, Marilyn Monroe's - Monica Lewinsky's for Pete sakes. But I think Judy would be a challenge ^_^
