I'm having hard time deciding between these thumbnails. Personally, the ones on the left (1,3,5) are the better half. 1, 3 and 5 all show the prime aspects of "Hourglass" and really convey the sort of impression she was meant to make on people.
Number one shows off the dominance I wanted her to have, being so powerful that she sits on top of her encased enemies.
Number three catches her ruthless side, as she smashes one of her "captured" subjects. Perhaps they didn't live up to her standards?
Number five brings out a more aristocratic approach to her, since she holds her head high and walks with class? Whichever it is, she looks like she really knows what she wants.
Now, all that's left is to pick one and create the two pieces required for submission.
