It blew my mind too when I first heard about it. :O

Good job Randy! I found in doing this demo that my first two "cross-hair" lines tended to lean, often, into the same errors. If we notice consistent deviations, we can lean the other way. That's one way to gain control of directions. It's analogous to noticing which shoe wears out more, and working to equalize our steps. But for many of us, especially with longer line sets, the first attempts are more like an infant learning to talk. Lots of wild variations. You are beyond that, as many who posted here seem to be. One of you mentioned putting random dots all over the page, then connecting them at random angles. That could be fun to go from short to long distances until you can skate the page triumphantly. In response to your question: Rote exercises may seem non-creative, but here is where you can make them creative: change up your regimen, weekly or monthly, to evolve it into your way of growing your skill for your purpose.

Good observation/question, Randy. That wide-angle effect (proximity) can exaggerate foreshortening — but always exaggerates diminution to the extreme. The amount it exaggerates overlap depends on positions that create overlaps, and a great big close thing sure seems to overlap everything behind it. Look at how your third example above accentuates the overlap effect by adding that fog-load of atmosphere between the close kid and the distant canyon. There is no question which is closer. Overlap, diminution, and atmosphere galore... to create bigness. But as I mentioned in our first work review, it is possible to treat a big subject, like that final example of the tall ruin, as such shallow space that the building itself relies almost entirely on overlap to show what columns are in front of another. This was good work, and if it creates some tension of "what's going on here?", it's doing the good work in you of questioning the illusion. Thanks for this!

Cheers✨

Same 🤣
