I really like the style of the illustration because it is high detail without making it overly 3D looking. The shadows and detail help the illustration pop off the page. We could do something like this for each item on our t-shirt.
Not exactly a rendering but these images show perfectly the reality of building, and how important accurate sections are in your drawing presentations. What are sections best used for? - to show the transference of traffic (people in this domestic example) between different levels or storeys. Actually, these photos are artistically, quite beautiful!
