Here is one drawing in Lesson 07 from You Can Draw in 30 Days by Mark Kistler. Lesson 07 is Advanced-Level Cubes. Ohh, I’m advanced now! With each chapter I learn a little bit more, but at this point I’m following step-by-step instructions for each drawing. Works for me.

Here’s the one from the book. Mine looks almost just like Mark’s! (Copyright belongs to the author Mark Kistler, his publishers, etc.)
