I am a big fan of Black on Black designs (the wallpaper in my living room is a black on black design) as they have such a wonderful masculine quality about them. They are also perfect for when you do want to just add one piece that breaks the colour scheme and instantly adds a glamour flash to a luxury interior design scheme. For me this is a gorgeous project but the interior could definitely do with that splash that just brings this house to a home.
For me it would have to be a splash of gold added to this interior to really give it that luxury feel.
I also love those textured interior walls... Dreamwalls do similar here!
