She's a great looking character and you can never go wrong with a Stonemason set.
I like the way the shadow hits the stairs. I do find the pose a bit too symmetrical and stiff though. I think this pose would benefit greatly just by a number of small tweaks... say a slight twist of abdomen and/or chest which would lead to a slight twist of the more forward shoulder and a slight bend of that forearm which you would counterbalance by moving the opposing side's thigh slightly backward, etc. I realize that dress's poke-thru potential might keep you from doing anything extreme with the pose but I think a few subtle tweaks would go a long way.
Still, good job.
