What I really love about the image is the subtle textures of the elements and how they are deliniated from one another. The wood presents stridations of straight lines, while the leave not only resents curvature of its basic structure but of the small pattern thats contaiend within. but feeling is this image wouldn't work as well in color and presenting it in B&W forces the viewer to focus on textures and shapes rather than color too.
