Such a breath-taking space. Neutrals in design are almost always gorgeous, particularly if you have loads of light spilling into the space, making it light up and glow. The cow hide rug is an odd touch. Though I respect the urge to add a little ruggedness and earthiness to ground an otherwise ethereal room. It can't be the only thing in the room not cream or blush colored. I say brighten the room up with some potted palms along the arches and darker wood toned items on the mantle or go with a rug that's a rougher texture but still in keeping with the color scheme.
