I thought I would add my first room design here. I kept the same floor demensions, added 4 walls and a ceiling(which is set to not render for the shot) I added three doors, two windows, some furniture and added a few wall lights and a ceiling light. I played around with the lighting a little but quickly realized I didn’t know what I was doing so I left it where it was.
Edit: I probably spent a little too long on applying the materials and playing more with the lighting but I am pretty happy with what I built and I learned quite a bit in the process.
