I'm a great fan of your work. I specially appreciate your use of various medias and subjects, not being exclusively a photographer of this or that, but a photographer. Better put, an artist.
This image attracts me for the sensation of movement which brings flying and liberty to my mind, as if I were a bird between the buildings.
The use of a pinhole camera contributes to the greatness of the image with its unique focusing and also what seems to be a double exposure. the colors give it a "blues" mood. The composition, with the space between the buildings being diagonal, adds movement to the image.
