Very interesting! This reminds me of the central thesis of “Drawing on the Right Side of the Brain” by Betty Edwards, which is that in order to truly learn how to draw, you need to render what you see, not what you know. Everyone can do it, but it’s hard for some people to see something as a collection of lines and shapes instead of a face or a building. Sometimes this involves tricking your brain, e.g. drawing from an upside-down picture.
