Those chairs are lovely- I noticed the accent wall and the area rug you currently have kind of match. You could place an area rug of a similar color, but in a plain or more muted pattern. You could also try complimentary colors, in this case olives, creams, or muted browns. As for the drapery- the roman shades kind of blend in with the color of the wall. Maybe a little something more sleek would bring out the contemporary and chic feel of the leather chairs!
