I whipped up a similar scene to last posts pen and ink piece using 3d tools:
It's not totally identical to the last piece but the features are in scale to the last. This is a quickly knocked together scene with misbehaving textures. The viewpoint in this scene is set about right for a 6' tall person walking down the middle tilting their head a bit to note the side corridor and steps as they approach. The whole thing took about an hour and a half , which includes kid related snow-day distractions and messing about with the camera shot and textures for the last 30-40 minutes.
