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.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

I agree that your small room can look beautiful. Your floor looks clean, and it is obvious that you wash laundry. Wash your shelves and dry them with a cloth. If your clothing will not get mildew, fold it neatly or roll it (fewer wrinkles) to store it on your shelves. Stack your books and papers neatly - either flat or vertically, depending on the moisture/humidity level of the air in your climate. I see that the wooden bed and another piece of brown wood furniture might benefit from some cleaning followed by an application of furniture wax. I see that the pink base for the desk/table by the bed would benefit from wiping with a damp cloth. Wipe off all surfaces of your chairs. I see that the wall near floor level is discolored. Find out what might be done to clean this. You can make this room clean and beautiful! Best wishes for success.
