I thought I had a good entry for this contest but then I reread the rules and realized that no licensed minifig parts are useable. I had this great hair piece that I wanted to use, but I determined that the hair only came in Exo-Force sets, which is not a LEGO trademark, it is licensed from Japanese animation.
Btw, space guys, the next Rebrick contest is called Great Moments in Space: https://www.lego.com/en-us/rebrick/contest-page
