16' long is a lot of room. Can you post a pic of the rest of the room? Remove every door you can. Every doorway does not need one and doing this one simple thing will remove a ton of bulk and make your space feel more open - no need to remove the hardware if you think you might want the doors back sometime in the future. Are you up for painting the walls and possibly the trim? Is this a sectional? If so, you might have to split it in order to get it to fit. The curtain into the bedroom is a good thing. I have used that idea, I love it, and I am not from India! Change them out for a lighter color and add panels to the ones you have - make them at least 3x fuller than the doorway. Pull them all over to the hinge side of the frame after the door has been removed. Your pictures need to be rehung and you can address that once you have found a furniture arrangement that works.

Thanks for the comment .It was a gut feeling that the sconces are too many in dining area .Now as you suggested I will reduce them to only two sconces on the bigger wall of dining area and 2 sconces on the wall behind sofa . It's difficult to give new points on the window wall at the moment .However if that would look better than I can go for that. What do you think friends .Any other idea

Priyanka, Wallpaper on doors is not a good idea. You can go for laminate panelling on the wall and matching laminates on the doors. You can choose a veneer as well. The space is too wide for a single door though. You will have to plan accordingly. I am assuming you are talking about the brown door and not the other black door in picture.
