Colour...objects of interest...lighting...all add "energy' or we refer to as "movement" in a space. Interesting pieces of furniture with different textures and different "eye-levels". For instance, you can purchase 3 or 4 different forms of seating options...you are in India so you should be able to find FABULOUS furnishings for great prices. You could purchase a low-slung sofa, an extra large "floor pillow" (it would act as a chair or foot stool), a leather-covered round ottoman and an interesting crate/box with a slab of glass or intricate wood over top...this is your seating arrangement for the living room and will work as a great "hang-out" space that you can enjoy by yourself or with a tonne of people hanging around! With all that visual "movement" from one object to another to another, you will create interest! And "interest" is energy! But your best bet for energy...people!

You will need space to walk and for your feet if you turn the chairs around - if you put a divider in you will block the view from the dining table out to the balcony - and thus make the kitchen and dining room both have no view ! So if you keep it open, the natural light can get through !

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.
