Hnm... First off, I love the pose, very cool, and the mist around her is incredible.
However, the sweat--while a nice touch--is odd here. For one it's to symetrical, it doesn't look natural, nor does it look like it's flowing with the curves of her body. It gives the picture a flat look.
Secondly, the pictures in all cool colors, so her sweating seems odd and bizarre. It's more fitting of having a nightmare than meditating. We need to be able to find some source of heat to explain her perspiration. Warm colors for the background work, or hot coals or a fire in the background, some source of heat.
