VERY nice. I think it's great the way it is. the hand adds interest and the illusion of action. and the light pull ornament adds a beautiful curvy shape that gives this some class.
Black & White was an excellent choice on this composition! The two fingers reaching in a pinching motion and the lamp fob really pop out visually from the black backdrop. The white of the fob really stands out from the surrounding darkness so when the viewer looks upon the title and sees the fingers reaching out to turn off the light we get a sense of the action of the present AND what will be after the action - darkness will envelope the illuminated scene. After looking at this for several more moments I am struck by how my mind can instantly equates the illuminated lamb fob to that of a light bulb because the shape of the fob & the fact that light seems to be emulating out from it. Good job.
