A quick little gallery scene I made, the spotlights use IES Data and the all the texture apart from the central painting one, are from LuxRender's materials database so i didn't pack the blend to reduce it's size. Rendered with LuxRender.
But I can see that you've lit and composited the scene PRETTY well..EPIC MAN!
Again, blendswap messed up the cropping, sorry about that.
