Living Room - Day & Night

I started using blender not long ago to learn to model, switching from Maya. This time I'd thought id give lighting and rendering ago and see what I could come up with. I've been following BlenderGuru for a long time but finally started to follow along and complete a couple of his amazing tutorials.

None of these models are mine and was sourced from different 3d model sites for free use. This project was solely for me to learn the render engine and material editor in blender.
