I wanted to address the room as a whole, so I tried to integrate the part that you aren't using now. Since the budget was so tight I couldn't get a seating area in there, but I included a nice bench to make the space not look so sparse. I wasn't able to include that many high-quality pieces because the budget was stretched too thin, but I think the comprise turned out nicely!
