You can go for normal marble finishing. and can go for installing a HD projector. You can visit ProjectReview. They have huge collection of projectors in different range. This will definitely give an elegant look to you drawing room.

I really liked the indirect lighting and the bar light fixture.

Thanks for your response and putting a stamp to what we thought. yeah thats the whole idea. We want to merge the utility with kitchen by removing the wall on the right of the utility door and also remove the door. We will keep the sink in the utility behind the wall on the left of the door. This will conceal the sink area from drawing room. Do you think its a good idea and will make the whole look of the house grandeur. We have also removed the wash basin from dining area and planning to remove the small extension wall between kitchen and wash basin in dining area. This will make the drawing room look bigger and more natural light coming into the kitchen from balcony side.

it depends on what kinda design you like - contemporary designs, traditional designs etc. Once you know that designing what you want becomes easy. Walls - you can have all white walls and one different colour wall. Sofa - This is the center of your living room and other designs and colour revolve around it. Pick sleek, sold colour sofas. A center table that goes along with the sofa and a big carpet under it. Curtain - curtain colours should match the sofa. Pick one spot for the study table, its placement doesn't look good.
