I deliberately chose a rather mundane subject and tried to stick to a photo-realistic style. I avoided any intrusive color-grading or post-processing and aimed as much as possible for subtlety. The scene is a bit lacking in small-scale detail and I doubt it'd fool anyone on close inspection. However, it was a useful exercise and I'm fairly happy with it. I initially considered Substance Painter for the materials, but I had a hard time UV mapping the rather flimsy structure, so all materials were done in Blender. They are usually a combination of a couple tiled bitmaps and procedural textures, which I manipulate using the useful Pointiness attribute.
