My house.....why doesn't it look like this

I am slightly obsessed with this image via Elle Decor.  I recently moved the lounge furniture around again.  The Voice of Reason looked at me pointedly and asked if I was sure the tv (and wiring) was not going to move again.  "Yes dear" but I didn't mention the art or the furniture.  Its much better but I am thinking of dropping the art lower on the wall like in this picture.

Of course I also would like a new sectional sofa (to watch said tv more comfortably) and I dream of finding the right lamp.  Where do all the good lamps hide?  If you know please share.
