Need to see the entire room if possible...why is the sofa in front of the small window? Can we help you with the layout?

I like your high vaulted ceiling! I would use this height with wide drapes as high as you can.I would get nice decorative pillows too. My idea of how to make pop up height with chic for your lovely room.

I can't imagine there isn't an echo in the room because of the lack of window treatments. I think the drapery treatments could be sheet so the windows could still be seen, but help provide texture for the home.

The drapes make your beautiful room gorgeous!

I got decor idea above the window from Rebecca Robeson design

If you only want a shade on that small window I would not put your sofa there run sofa other direction and add two Chairs flanking the small window.

The couch in front of the window looks odd--the drape idea is really great, if you decide the leave the sofa there.

Is that your main sitting room in the background past the chest and plates? Are you sure you can't just use this room as a dining room? Looks like the chandelier is centered and would just need to be lowered above the table. You can still use the adjacent walls for casegoods and art.

A pair of china cabinets flanking the French door would look great. Then a pair of demi-lune tables with art above could flank the single window.

Sconces make great wall art and are functional too. Many sconces cast patterns on the wall when lit for a beautiful effect.
