HGTV-type Ideas?

So the are walls are a little darker (sandy yellow, I believe) and our new furniture is in (although they had to order another sofa since this one is broken too) but I need help!
I have no idea what to hang on the walls now! Also, I want to find a tall lamp for behind my chair. The walls you can see are plain and also the wall on the other side of the doorway into the dining room. Any ideas?
And if anyone would like to pay for new flooring, that would be awesome!
