Rowe Furniture has very clean line sofas that I think would be an appropriate scale for this room. LOVE the red feature wall. You do need to bring the red into the room but knowing how you want the room to feel can help determine a color palette. If you want the room to have energy and "pop", try a split-complementary or triadic color scheme. If you want it to be more relaxed and harmonious, I would suggest an analogous color scheme.

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.

OK, In the future If I need then I will contact you. By the way, all the sofas are looking fabulous. I had purchased a modern sofa set from Oriental Creativity at a very suitable price. I just love that sofa.

I like what you did on the previous TV wall, a lot. Now I suggest, let that be the only piece of bright colour in your space, and pull designs for cushions from there. I suggest colour rest of the walls (+Doors on the side facing the room) in a neutral, warm white, matte finish color. The wall behind the blue sofa, is it tile? Can it be coloured over? Also, are you in a rented space or is it your own house? That would help understand if you can make semi permanent changes.
