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!

The "Other" category in Houzz is not monitored by most people who answer questions. If you will repost over in the Design Dilemma area, you will get assistance. I don't know if you can delete this post or not.

A houzz contributor, not too long ago, had made a wine rack out of 4'x4' wooden pallets, that are used in the US to move a load of goods with a fork-lift truck. Perhaps they have them in your country. He cut them in half so they were only two feet deep and stacked them up to high counter height. The wood would be a nice contrast with your concrete, might add a little warmth to the space. cascio.offsite@gmail.com

If you love that wallpaper, use it in bathroom. Not really right for behind bed. I would go a drum style chandelier. In a silk pale gold. Your bed looks zen or Asian to me. I love it. But, you don't. Need to much with it. Keep it simple a more formal drape on windows, color would depend on wall color and bedding. I'm thinking a dramatic peacock satin. Use a lighter same tone on walls a rich teal. Ceiling can be gold leaf. With alight that cast shadows on ceiling at night. Then your wall paper will tie in. Furn should be mirrored.
