If you look at projects developed with Blender with architecture or interior design as the subject, you find lots of fantastic artwork. One thing that I always try to find with those projects is additional information shared by the author. It could be a list of settings or a trick to solve a problem, which is the kind of information that can make a lot of difference in a later project.
Here is a simple project from artist Caique De Moura with a modern kitchen design.
Besides being a single render of that scene, you also find in this project some interesting screenshots of the scene in Blender. One of those images shows the entire scene set up with the background and the location of the lights.
It is an excellent resource for people trying to develop their skills in architectural visualization.
