I'm extremely pleased with my Remix. They've based it on a small throwaway Buffyverse/Narnia drabble (Running Though A Winter Wonderland) I wrote years ago, and expanded it both forward and backwards wonderfully - and even thrown in a bonus unexpected crossover as well!
Through the Wardrobe (The Three Worlds Remix)
Oh, and my remixee seems rather happy with my story. I'm more than a little relieved given that I'd never written that fandom before. *happy smile*
