Here is another view of room

you have a lovely room and your antique sideboard is beautiful. I noticed that you have an acrylic chair in the corner which makes me think you like both antique and modern. that said, I would suggest going modern with your chandelier to juxtapose the antique... not sure if you are open to changing out the chairs, but the color and style seem a little more country to me vs antique or modern.... if you had more of the acrylic chairs, I would use them for seating. here are some ideas for chandeliers.

You need art!

Do you have the curtains up now? They are too short. You could adjust that by lowering the rod to the molding, just above the roman shade. The panels should be on both sides of the window. I like the chandelier you have; just lower it to 30" above the table. Remove the mirror over the buffet, it is too large and you don't need 3 mirrors in the room. Also the silver frame doesn't really complement your other elements. Get art for over the buffet. It should be about 2/3 the width of the buffet.

Thank you. Great feedback
