Freshman Drawing Day 1 Prompt

I taught Freshman Drawing at a certain art school, and this was the prompt I gave them at the first day of class.

This prompt originated from a 3D Design professor I had who was notorious on campus for her harshness. She gave me a lesson that I think about in every drawing I do to this day. xoxo Prof Lieu
