IMo there are some things I would change , one is the lighting there is no way those work above a dining table and really how many clocks do you need . A piece of art in the LR would be a much better thing on the wall and in the kitchen leave that space empty ,if you want to have color on that wall you will need it to connect ot something and right now I see nothing with color in the kitchen and the only thing in the LR is the rug and even it is pretty neutral. I would take the sconces away in that dining get three fab pendants to replace those fixtures in the ceiling and then decide if you need anything else.IMO you need some color through the whole space you are lost in neutral land and it has a nice feel but truly pretty boring. I would start with the art in the LR add some pillows in colors from the art and see how that goes. Because the whole space is quite light i would probably not go too crazt ywith the art but something like these would add the color without being crazy.
The first and the last have the best colors to pull from
