I want this room so badly.  Walls would be either a marshmellowey cream color or a deep charcoal situation or if I was feeling ambitious I'd upholster the walls in a metallicy linen, following the awesome tutorial on designsponge.  I would add a cool thayer cogginsesque sofa in a tiger stripe upholstery like this. I would layer this beautiful Ousehk rug over gorgeous hardwoods and a neutral knotted jute rug, like this one at IKEA. Accessorise in brass|rose gold mercury glass|tortoise shell and this room has just gone from an idea, to a full on necessity.
