Why do you only sell metal prints?

I prefer to have my work printed on metal because of the depth and vibrancy it brings to my images. Looking at a metal print hanging on the wall looks more like looking through a window than looking at a piece of art on the wall. All of the metal prints I make have a float mount (on the smaller prints) or an inset frame with a hanging wire so they stand out from the wall which heightens the sense of depth.
