An interesting architectural item, but I think you included too much. It might be more interesting if you zoomed in on one section of this sculpture and really brought attention to that part. This would be nice for a postcard.
Not only that, but you'd be able to make it horizontal which would be more applicable to use as a monitor wallpaper, and enticing more Caedesians. Despite any of this, however, it is a magnificent piece of sculpture and your DOF, color treatment, and utilizing the perfect sort of light to get definition in the shadows, turns this from a photograph to art. Technically gorgeous.
