You have all the reasons to redo the house, its very lifeless and looks worn out. I feel creating a separation will terminate the spaciousness of the room. Adding colours will surely help, Since you have a tan color sofa,I suggest grey, white or light blue color on one of the walls. Add some art works of the color you chose for the wall. This room needs some fillers like , books, throws, candle stands tall and lean. YES DON FORGET 1. Mount the tv on the wall make some space on the floor and Fix a large size mirror ( Wooden Frame if you can afford).

If you can't clean up the painted edge, you could always add a 1x3 piece of wood as molding. You can even carry it up to the ceiling to frame that wallpaper. I don't see that paint color in the wallpaper, or maybe it's a lighter version of the flower centers. Maybe stencil on a design using the darker color, or another color from the wallpaper to help tie it together. Then narrow floating shelves or vertical frames or something in the painted areas it you feel you need it. Maybe turn the bed around so the wallpaper is the headboard.

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

I personally would like to see you start your art collection. It may take a while but you will get there. And the hunt is tons of fun. Do not worry, about who made it, only that it is original or a signed numbered print of maybe 200 and that you love it. sources, etsy and Saatchiart. oodles and it changes all the time. often $100 or less. both under $60 etsy a few of the myriad ways to make your own Butterflies or some other small collectible natural or otherwise One large on subject matter, then small ones regarding that topic framed important things in your life magazines, album covers important newsprint that means something to you Bandanas, or how about the decorations off your favorite clothes before they go out. plates, or mugs, judgin by your couch, these are not it, but there are some really cool modern ones too large copies of musical scores. hope it helps
