I would put the TV on the wall you have the sofa on now and use the larger wall for your sofa. Right now it looks jammed into the corner. It should be fairly easy for the "cable guy" to move your cable outlet to theother wall if you don't have one there already. Or an entertainment unit would be better for your TV set-up on that wall.

You don't necessarily need only paintings as artwork. You can put some floating shelves near the dining space with some good crockery like plates or tea sets which can be used for occasions as well. On the wall in the living space you could keep either traditional or modern show pieces.

house is good in white. ensure you choose off white colour such as cotton woll and not brilliant white whike repainting. Gate in black. boundary wall in mud colour. overall it would look like a spanish villa. only thing missing is a big olive tree or a palm tree

if u are interested in art work.. you should definitely go for some bastar art pieces.. beautiful vases in contrast colors to the dining area will also comprehend the look
