I would probably put a sideboard there, with art above.

Your art by the dining table is too high. I'd choose a single large canvas there and hang it at eye level--eye level when you're sitting down.

you could do something shallow against that wall, find some nice art pieces to hang above it.

Ikea hack.

maybe make it a beverage or coffee bar spot

these are unfinished oak base cabinets painted white and sitting on a platform w/trimwork.

you have a lot of wood colors in that room. I'd actually paint all of the wood baseboard and door molding to white. that dated oak stain coloring really doesn't work w/the cabs, flooring and beam.

I'd also try a different color on your wall.

Well, I'm stumped from looking at those pictures what the "style" of the home is. So I will reserve comment on what kind, but I would put some type of piece of furniture along that wall to be used for additional storage. And then to me the dining table needs to be bigger, and it needs to be put in front of the window and run going the other way. And then move the chandelier to go over it.
