I like the fact that you made Leia a slave to a Sith Lord instead of Jabba! Interesting twist! I always wondered what it would be like if she became the Emperor's slave girl, and though Vader would be fully aware that she's his daughter, his mind would be so twisted, he would let the emperor keep her that way.
Great abs and frightened face on Leia. Might be interesting to do this with a Gamorrean Guard or Bib Fortuna (even Boba Fett) holding her chain. Would evoke the moment of her enslavement in Jabba's palace.
