Makeup is applied well and her look is solemn. I feel her iceolation, I almost tremble for her. What bothers me is the lighting. It's not moody enough to give off that feeling you were looking for, I think. Putting the left side of her face in deep shadow and darkening the background could have achieved that feeling of isolation or desolation.
Not a fan of the title. Ignoring that, it is a nice photo, I can feel the cool seeping into her. Assuming you had some for of diamond necklace it may have fit the theme better than the perls. Flash shadow is a minor distraction.
