An interesting point about the possible crop. Just doing it on screen I realised my eye fell immediately to the silhouette of the what seems to be TV with loop aerial on the leftmost area.
I like the take on the theme here. The silhouettes are great. I don't know if you have tried cropping the pic so that only the white canvas and the black silhouettes remaines. I'm not sure it will imrove the pic or not, but I think it's worth a try.
