These three pictures really took advantage of different angles/framing of the room. They look so much more interesting than just a "here is all of my living room in one shot" picture, while still giving you an idea of the space layout.

The way these two photos use light really enhance the feel of the rooms: darker for a masculine room, light and bright for the fun dining room.
I think the processing on these pictures (which means editing after the picture was taken). It really gives them a distinct "look."
