Artwork is a great way to infuse a space with color and life without painting the walls. You can always move your collection from room to room as the mood strikes you.
It would be pretty to put sconces on either side of your mirror - i.e. the lights on either side of this art. Also, we could find a piece of art/ or pieces of art to put on the opposite wall.
