All The Way
If you really want to make a statement, a large artwork can do wonders for the atmosphere in your home or office. Especially in a spacious house or room, a large work will have profound impact, and give personality to the space.
If you have a large living room with large-scale furniture make sure the artwork is at least two-thirds the size of the sofa or sideboard. Having pieces that are too small or too large will make the whole arrangement look strange.
With larger pieces, allow room for people to step back and admire the work.
