What kind of budget and style are you looking for?

Oh, the table is fabulous! You can easily achieve a more contemporary look in this space, and a new chandelier and window treatments will go a long way towards that. I wanted to suggest perhaps considering a large-scale piece of art for the big wall where you currently have the long, narrow piece. That's the perfect setting for something very striking. I like your current art, but feel that space may be crying out for a bigger, bolder piece.
