The chandy is a bit over the top compared to the simple pendant seen through the cutout. Neither of those fixtures speaks "Med" to me. That chandy is suited to your dining room table and chairs, but since the dining room opens to the foyer, you might want the two lights to better compliment each other. I'd remove the art between the windows - looks to be crowded between the drapes and the black frame isn't working in this space or on the mirror in the foyer, which looks a bit stark and contemporary. The tall cabinet is also a bit too contemporary feeling here. I'd refrain from wall paper unless you'd want to paper the interior of it for an accent. It looks to be good quality, so you probably don't want to paint it to match the dining pieces. I think the spaces would be more interesting and warmer/welcoming if you painted the light walls in a couple of tones from the same color strip card to add a bit of life. Can't tell how open the dining is to other spaces, but you seem to have a green palette started there. A background color would pop your white furniture.
