ART IS PERSPECTIVE
Art is perspective. The meaning of art is always changing, depending on how you look at it. From a forwards perspective, we see the man holding a bullet shell, with a backdrop of buildings and the sky. From the back, however, we see people are added to the equation, some of them even inspecting this interesting sculpture as if it were from another world. We also see how details in the back are just as important as details in the front.
I love these pictures, Matt! Just an FYI, if you create a gallery with your images (check the instructions at the top of the High Line Page), we can see full size images as well. Let me know if you need any help!
