Like the person's silhouette, but the darkness, dirt on the window and some sort of reflection on the bottom half of the window take away a lot from this shot for me.
I'm thinking the light bar is the reflection of a desk or office light. Can't tell why the observer had her hand to her face - doesn't quite look liek she's on the phone. The area being observed is rather dull.
The composition would have been dramatically improved if you had more of the subject's profile in this. It's dark but does not seem to convey any mood. Although you probably put a great deal of thought and effort into this, it just doesn't look like it to me. Sorry... :(
