Love this look for a separate formal dining room. The rich charcoal walls with same trim are gorgeous. Gilded frame display over buffet and gilden mirror are nice contrast agains the dark grey.
The casual french farmhouse chandelier and natural fiber rug keep the room from becoming too stuffy for today's modern lifestyle.
I'd ditch the fabric table covering to go for a more youthful feel. The white fabric makes the room feel less liveable to me. I don't like museum rooms.
Without the white table cloth this room may need some white accents, perhaps iron stone on the table to keep from going too dark. Good lighting, a lamp on the buffet or sconces would help.
I can't really get a good view of this art. But I'd go with modern sketches, to balance the antiques and deliver a more youthful modern ecclectic vibe.
