Blender Living room render

I’m noticing a common problem in this, the floor is WAY to smooth. It looks like it is a smooth as glass. Try bump mapping.

How does this look:
I fixed the light, the floor and rendered it in luxrender

It’s Noisy and to dark.

Nice render but the window bugs me it’s too low and too deep change the windows and lighting and it should look much better a brighter scene would really help
