The smoke gives a pinch of bohemian atmosphere and thanks to cigarette in her hand you look so much more interesting, independant and somehow thoughtful. Besides otherwise we would get another pic of 'look how cute I am'. Watch
This is an awesome portrait IMO, the model is beautiful the natural light falls just right (I love the way it enhance her right eye) and the smoke adds something (eventhought it's bad for her health ). Faved!
