Living room help

So I got some good advice from some when I needed help with my bedroom setup, and now I need help with the living room. I painted one of the walls, and kept the TV where its at, now I have two shelves that need to go up, and I want to get some type of photo up as well. I pretty much will print the photo out myself, and put it on the wall, so Im basically looking for some help with what type of picture should I put on the wall. In the bedroom, I have a picture of Paris, Times Square, and a Greek island, but I dont necessarily have to go with that type of picture in the living room. If anyone has any ideas, please post them. Im thinking not that big either, because the two shelves are pretty big.

Here are pics of the wall and shelves. Go at it!
