There is light coming from the left that destroys the silhouette. Based on the shadows, it is either street lights or light from a building or a remote-flash firing? 6.
There was absolutely no light from the left. Trees are illuminated from the right and shadows on the street are -as well- caused by light from the right.
Anyway, it wasn't intended to produce silhouettes. They weren't asked for. I think the picture would be (even) less attractive as pure silhouettes.
Thanks for the most detailed comment I got in this challenge and points that increased my avarage ;-)
