I originally built part of this room in 2016 as a practice scene for V-Ray lighting.
I decided that I'd like to see how I could improve upon my original attempt.

I used V-Ray hair and fur for the rug, RailClone for the floorboards and Marvelous Designer for the blue piece of fabric.
This scene uses models built by myself (the fireplace and firebox) and models from various sources, primarily Design Connected.
Textures are from FriendlyShade, cgaxis and more.
