Yes, I know about the floor :( Thank You Inna_Inas for Your great advice. I will try it next time :)
I like mix of dark colors and the view is stunning! You got a little mess up with floor - different layers are visible through each other. Here's my tip to avoid it. First I make flooring that I want to use in my design and only after that I divide room with another walls. That simple act might help to keep floor with one texture without overlapping it with another types of wood or other materials.
