IMO a large art work on that bare wall is all you need and as for a buffet could you post pics of the rest of the living space that will help with ideas. I love what you have so far other than I do not like fake flowers anywhere , blue is aninteresting color to work with and I would need to see the rest of the space sbefore hazarding a guess. I also think captains chairs are a dated look especially inyour space which is leaning toward contemporary.Why not try a blue vase in the alcove above the frieplace for a start .The art could also have some blue and then see what you would want for more blue.

There are no fake flowers, they are white shells in the shell vase on the fireplace. You are seeing the whole room. Shorter wall is what I'm thinking for sideboard or buffet 60-72" is all it could take. So you think upholstered arm chairs at the head of the table are dated? What would you suggest? I am thinking 8-9' to 12-13' area rug under the table and let the rug dictate the color for the end chairs and artwork. Your thoughts?

Perhaps captain chairs are not the in thing right now but do you really care about that? They will be comfortable and look great in your dining room. All matching is also dated and the ship has sailed on having all different chairs. I like your idea of pulling colors from the new rug. I think you have an excellent start but I also am not loving the shells in the shell vase as it looks granny in your contemporary space. You certainly have the room for a sideboard which would be a nice functional addition. Do you have anything in mind?

The shells/vase are leftover from Z Gallerie so I didn't think they were out of date. Yikes! I have no idea about sideboard except NOT dark wood. Thoughts?
