I wouls get rid of 1/2 the pillows on the sofa too matchy add an area rug that is bright with some other colors to use for accents you have IMO too much brown so I would do blue drapes in the DR take the cloth off the table and add a blue and orange glass bowl for a centerpiece filled with green apples get some pillows in green and orange and a big piece of art work for the wall above the sofa and maybe a mirror on the DR wall and a fabulous light fixture for the DR an arc lamp behind the sofa in the corner so it comes out far enough into the room to light a coffee table.

I like to style with both wall art and lamp.. But if it has to be just one item, it'll be LAMP.. Always!

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

Hi, That's a good space you have there. You can try some floor rugs and comfy chairs to decorate this room. Floor lamps for your living room décor could also work well for this space. One suggestion, though, while decorating your living room, make sure that you also add an artistic touch to the wall. Either wall art or wallpaper, or even a chic mirror can work wonders on the overall look of your room.
