My first thought for this category upon seeing the "larger than minifig" scale requirement was Scala figs... What could better represent a stereotypically "girly", Barbie-like category than a Scala doll?
To play with the scale even further (and mess with your heads), I used parts from several different Lego scales: Modulex shelves and drawers, System walls and chairs, Friends lipstick tubes, and of course the Belville and Scala accessories.
YES! There is a man among the boys! An excellent scene. This was my category and honestly, I was starting to think I'd never see it built in. You have done a stellar job! 5 points mate! Grats on the perfect score.
