I did Kistler's Lesson 4 today and as you can see below, my globes somehow changed their shape. They turned into... squares! It's magic!
After some introduction about drawing squares (just by eye measure, no rulers), I had fun doing the bonus tasks again. One was to draw some real life box study. That's a tissue box from my bed table. I didn't really flesh it out, but that wasn't what this task was about, anyway.
And several overlapping spheres - just like I did with globes in the last post!
