Sorry about the noise. My very first LuxBlend render. Some models are from http://blender-archi.tuxfamily.org/Models , I don’t claim them as my own. Enjoy!
“Sorry about the noise”? There is no excuse, keep Lux render longer and don’t waste our time with this noisy rubbish.

Eheheh, just kidding, nice picture, maybe it could improve with some more details on the scene. What about some frames on the walls?
What sampler and integrator did you use?
