There's a Sinix video called "Drawing like a Painter" that your nose example reminded me of. In the video he draws several recognisable portraits using only the shadows cast by different parts of the face. What we're doing is significantly less complicated than a face, but the concept of using the shadow a form casts in order to define how that form sits in space is the same. There's also this image that I found in some of the lesson 2 critiques that also demonstrates that you can have something that approaches a line but is still actually a shadow shape.
