I like the ceiling. I think the hanging lights are too fancy and distract from the ceiling decor. A simpler light would look better or sticking with the canned lights you have. The walls have too many big, black things on them. It's hard to tell if they are windows with shade --- in which case I'd pick something lighter, perhaps to echo the ceiling, TVs (how many do you need?) or what. I'd consider a big piece of statement art in the place of at least one. If you're on a budget, get a large, high quality photo in the right colors, you can take it yourself. Sepia and black architectural might work. I like more color and more natural light. You may have closed the shades for a better picture, so it's hard to comment on the light, plus windows are a feature of your room, not exactly a decorator's choice. I would consider how to get a few small pops of color in, pillows, flowers, candles, maybe even a runner rug along the right wall. If you are doing this as part of a portfolio, the entire ensemble would look more welcoming with a few touches like someone lives there. Something on the coffee table, for example. A few books and a candle. A tray with tea things, a vase of flowers or basket of fruit. Pick one or two things and make it composed. You see this a lot in designer Houzz photos. Here's an example, you note this picture would be a lot more stark with an empty table: https://www.houzz.com/photos/21-house-contemporary-living-room-san-francisco-phvw-vp~60642

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

i Walls are painted off white which I would love to retain which makes the room very bright. Dinning table set have been bought in mahogany finish with orange Upholstery for chair. Remaining furniture’s are yet to be bought. I have a show Pieces both modern old with a good collection of books. i Need your guidance sir.
