As an artist, I believe it's crucial to be able to draw quickly, especially with live models. It sharpens your mind, enabling you to capture a person's character in just seconds.
Stepping out of your comfort zone is important as it provides a direction for growth.
With this in mind, I'm planning to attend more sketch sessions. :)
P.S. Today, I drew Vincent—a non-binary person. It was my first experience drawing someone who identifies as non-binary.
