This is a revision of my submission for the ArtStation Lightbox Expo Environment Challenge. I changed the style to outlines and some tones only rather than painted, and added another angle.
The original theme was "Box of Mystery". I love architectural structures that seem to break the laws of physics and engineering, so I wanted to use an existing engineering marvel, the pyramid, as the main structure, in a way that would baffle anyone as to how it was even built, defying the laws of weight and gravity.
Modeling the structure in 3D was important to get the scale and perspective accurate in all angles, so I had to learn Blender in the middle of the project. It's really fun and much easier to use than I thought!
