You can mirror sofas group . And place large tv on the wall center aligned. You can see it from dinning and living area

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.

thnks. I actually have a family picture wall in the same room which is combined with dining area. So not sure if adding more wall Art will make the room look picture full room. By any chance the full wall to wall bookshelf will go well? Or mirrors or u still suggest wall art over all?

I think kitchen and eating area should be next to each other and kitchen should be near or next to an entry for ease in putting away food stuff. The sitting area should be near an outside view to add relaxed vibe to area and the TV should be opposite sofa for easy viewing.....sometimes necessary to move the TV and rewire accordingly. Good luck.
