Is there a question? This is a lovely monochromatic room however you need some light colors & more accessories and art to bring it to life.

Replacing your shutters with plantation shutters would be costly. Maybe some stationary panels would be a better choice. I'd want the Chesterfield in front of the FP and the chairs at the windows. You have to leave room for accessing the door so it makes you shove the sofa to the left. This room requires total balance.
