I agree with painting the doors. All my interior doors are a deep charcoal grey. You'd be surprised how expensive it makes them look. That aside I would start with a rug. A huge rug. Something chic with a lot of color. Then add love seats in white, colorful pillows, and chairs in fabrics that pickup the colors in your rug. No BIG furniture. Just because you have a big room doesn't mean you need to stick a brown sectional in it. A couple fancy topiary would look great under those windows. And dont forget lighting.

Not sure if i would paint it white. Try an off white maybe, but i would keep the chair as is and try a mustard gold plain fabric for the upholstery and place a red cushion on the seat. We would help you with more colour ideas if there was a picture showing the rest of the interior where this chair is. red scatter

Priyanka, Wallpaper on doors is not a good idea. You can go for laminate panelling on the wall and matching laminates on the doors. You can choose a veneer as well. The space is too wide for a single door though. You will have to plan accordingly. I am assuming you are talking about the brown door and not the other black door in picture.
