Lighting is dramatic on this portrait, but I don't feel the profile conveys the emotion your title portrays. Perhaps a straight on shot would show that a little more.
Good composition and lighting...however, the light on the nose seems to make her nose appear larger than it is on the tip (and just above the tip) and a bit disproportionate to her other features.
I like the minimalism of this low-key shot! It's too stable to really match your title, but as a result has a true Classical beauty to it. I'll start it at 7.
