What do you guys think? C+C appreciated.
Too dirty, rise a contrast and change colors a bit, and you will have a nice bricks tile :D But its surely not wood.
Standard fare, I would say.
Perhaps the individual pieces should be a little longer.
There really isn't much else to say here, other than to make sure that the walls don't blend in with these floors (this is usually a palette problem to figure out)

General rule of thumb: Lower contrast for floors and higher contrast for walls (comparatively, anyhow).
