I'd suggest dark red curtains if you need curtains at all -- the windows are beautiful as they are, and I'm not sure whether some kind of blind might not give you the ability to darken the room when you want to. On the wall, if you are real fans of any movies or TV shows, three big posters would be fun. Otherwise, I would still suggest using three pieces of art there of that size, all equal in size and somehow relating to each other. Three floral works, or three works in the same style, perhaps. I think a large plain textured rug in a light neutral from one of the cushion fabrics would tie the space together well. You might also consider a lovely low coffee table on the rug to lay out your snacks and drinks for serious media nights.

Consider Grey or white. U could also use geometric or any pattern in mint green

So I am planning to do something like that in the picture. I really liked the use of the emperador marble and the balancing of the colours. In the second picture, I have selected the emperador for Wall as shown in picture, the light ones will be for the next three walls and the third tile will be for the flooring. I hope it'll look good.
