Symmetrically hung artwork makes an impact as in this example of artwork in an entry way.
This really caught my eye- I love the coloring, but also love that the sofa is arranged under the artwork rather than the usual way - with the artwork balanced within the width of the sofa.
And last but not least-- One large impacting piece of art used in a small area.
