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.

Both the laminate and flooring are beautiful, but I don't think they will compliment each other. The flooring looks to be red oak and as it's name indicates has a lot of red in it. The laminate has a rustic feel and could be imitation walnut which is very neutral, wide grained and has no red. I think the lam would be fine with the paint, but not sure about the floor color. Are there other options for laminate wardrobe? Or do you have an option for flooring?

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

Trick is not to choose bright white or standard white but something with a tinge of yellow or green. Cotton wool colour L104 by Asian is a great example we have used time and again. Most emulsions come in matt, including the most economical ones such as Asian Tractor and Apcolite. Don't let the price of a paint fool you.
