Love your dining room table and chairs.....................they don't make them like that anymore. Perhaps you will consider updating the appearance with a unique paint job instead of replacing it. I would leave the top in it's current finish, but chalk paint the apron and legs along with the chair frames. Maybe replace the fabric on the seats.

It will still work with your pendant fixture. I even like the pattern of your drapery.

What I'd advise you to change is the color of the walls because I think the color lacks depth for such a lovely room, and if I was able to see a close up of the drapery could maybe suggest a color paint for your walls. And though there is a group on this forum will this is blaspheme............ I would eliminate the corner cabinets.

Once I see the pattern of the drapery, I can better suggest a rug for the room. Good luck.
