I don't see any empty space. You do need some lamps

I like more space than stuff, so I'm afraid I'm on your husbands side on that one. Also, I don't like a coffee table. I have tiny side tables and they work great. Bonus is that I can easily move them around for what I need (putting a food tray on, putting drinks for guests, etc). I would add a lot of colorful art on the walls. Get that from a local artist, or art gallery. Some colleges have their own art gallery as well. If you can't get art from there, try art.com. Order a print and have it framed locally with plexiglass. Wait to find peices you love. Art not only reflects your personality, but also is a conversation peice for guests.
