I saw a guy saying that a silhouette has to stump us and make us imagine a history for the object...your photo does that with me but i think it's little noisy and i'm not a huge fan of your bokeh! Good idea though, creative one!
I'm sorry but I don't think this is very well done. With points of light behind the bokeh would have been very strong but the dull blanket (?) doesn't add anything for me.
