Are you aware there are artistic styles beyond photorealism?

Yes, but in that case, as this article argues, you'd expect something that looked good. https://static.wikia.nocookie.net/teentitans/images/e/e3/TTO...

The Honnecourt illustrations strongly suggest that (a) photorealism is the goal, but (b) Honnecourt doesn't know how to draw it. He does things like place a person's right eye at a different angle to the rest of the face than the left eye has. But hey, how likely is it that viewers will notice a malformed human face?
