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.

Susan, I find that people often make their coffee tables too low and too small. Measure the height of your sofa cushion and pick a coffee table that is a similar height. Also, in the layout you posted above the room would look better with a larger coffee table. Even as long as your sofa, or close to it. Let me know if you need one custom built, it easier to get the right thing for your room than you may think. Here is my etsy store if you end up needing one custom built. www.etsy.com/shop/MetalTreeFurniture

Hi Nishi, Beautiful furniture and a very cute cosy nest you have. To begin with replace your existing coffee table with a hard wood simple coffee table. Replace your cushions with an assortment of pink, turquoise and golden yellow in different sizes and shapes, this will add some brightness to the room.Replace the pictures on the wall with a big mirror as per the wall size and add a nice frame to it. On the shelf on the picture wall place the candle stands currently on the centre table. The stools can be replaced with a nice upholstered ottoman bench in a printed fabric as sofa is plain. Cover the entry door with curtains as well so that it gives an illusion of a single wall behind. Since the wall behind the bench is already textured do not put anything on the wall. Remove the white bench there, instead put two big white teracotta pots there of different height and put bamboos on it. Finally put a blue/brown shaggy rug below the coffee table to complete the look. Hope you find the suggestions useful. Also you could put a few glass shelfs on the wall behind the 3 seater and place all your small knick knacks on displayLike how I have done on my wall
