Can you post additional photos of the living room? Wondering if you could switch the sofa and loveseat.

That chadeleir is hung way too high and not centered on the table so that will need to be addressed first. I think a linear chandeleir would be nice. I would do solar shades on the top windows to protect from UV rays and heat then the bottom ones can be nice roman shades in a simple linen fabric.The art in the DR needs to be much bigger and then choose a color from it for accents. A more vertical piece of art above the fireplace would also be a better choice.Please make sure no matter what light you choose that the bulbs are lighting the table not the ceiling

That Darden chandelier doesn't look fresh or lively enough. Your dining area has a bit of "church pew" going on, and you don't want to make that worse. Also, the style of the Robert Abbey chandelier was hot a couple years ago, and is waning. You don't want another post in 4 or 5 years saying "2016 called and wants its chandelier back". I think you'd be better served with something more classic and light, like the first drum chandelier that jck910 pictured above. I also think Patricia Coldwell wrote some nice ideas to make everything more cohesive.

Perhaps remove the candles from the mantle and replace them with colorful pottery.
