Great room:-) Number 4 gets my vote. I don't like the down lights in a dining room because they throw shadows on people's faces that are unattractive. Just a note to ask your realtor about the drapes. Everywhere I've lived, when we sold whatever curtains were hung went with the house (the contracts are standard in that way). And the thing is, the drapes really make that room fantastic, so I'd want to show it with them. Maybe you can the realtor put an exclusion in regarding the drapes, so you can still have them hanging during the showings.

How devoted of a housekeeper are you? Although I like the crystal look, I can't imagine the upkeep. Is this something that you would lovingly do to enjoy the look, or a chore? I ask, because I am thinking of replacing my dining room chandy, and even though I love the crystal look, I shudder to remember how much work it is to clean one that I had at my former house. And I was young then. I can't imagine doing this in my 50-60-70s and having the chore on a ladder for 2 hours twice a year to clean it.

The reason I don't LARGE face-on photos of family over the fireplace is it just seems like I am being stared at, lol! On the flip side, I covered my mantle at my old house with SMALL photos in ornate frames of friends and family members. Then a large picture/wood block print I loved in the center. I had wall mounted lights that looked like candle sconces on either side of my art, something you might consider., (either the lights or the sconce, well out of the way of little kid hands). That corner curio cabinet is GORGEOUS and I would put something on the mantel with a brown wood tone to tie in with the cabinet. Maybe a picture with a brown frame or some art with some color in it including brown. Or consider adding some colorful art or something on the wall kitty corner from the fireplace, so the room look a little more balanced. I don't see anything wrong with the sailboat photo, but then we are sailing people and love boats and the water and have spent considerable time thus engaged. If you're land-locked and have no association with boats, then it is a little contrived but will do until you find something that speaks to you. If it were me, and I had traveled the world, I would want pictures of that somehow. I have a large travel advertisement picture of a famous place I visited (Valley of the Ten Peaks in Canada, which is often used in Canadian tourism advertisements) which hung over my couch in the living room of my last house, and was surrounded by some other art pieces evoking the northern Rockies. Which made the space feel welcoming to me. Not saying you should copy me, but just sort of showing how you can develop a theme of stuff that reflects your live and loves in your "living" room.

I have that same light in a breakfast nook & i just recently added pendant lights in very close proximity. Like you I worried about matching but These 2 colors ended up looking great together. I would have liked to have added some of the aged brass color but I needed the darker bronze shading to help tie my areas of decor together. This info may not be helpful since you are looking for a sconce though.
