Your wall arrangement is looking good. I think the two candle sconces are too small for it though. Would take the ornate mirror on the right somewhere else in the room and let the eye rest between the window and the pictures. Would also move the large frame on the left., I think the center is where you should leave it. As for window treatments, I hope you plan to remove the vertical blinds as they tend to be dated and industrial. Consider just banding your drapes with the solid gray of the striped fabric. You might also look for a Moroccan tile pattern fabric in your colors for curtains and chairs, or for an area rug. Here's a pretty drum chandy and they're using a nice accent green. You might want to look into an accent color to pop things a bit. Also think a touch more black in the lighting would look good
