You could place a short cabinet or shelving system (about 25 - 30 inches of height) at the entrance, perpendicular to the door to create a gully / foyer look and hang some decorative hooks on the wall perpendicular to the door. That should give you a feel of dedicated entrance.

Next, you can move the sofa to face the windows, move the book case to the wall currently hanging the mirror, and add an accent chair there to complete the nook. Move the whole mirror setting to the original bookcase wall. Paint the window wall in an accent color to make it the focus of the room.
