You might think that because we’re so familiar with the shapes of the body, that they would be extra easy to draw. Ironically, they are the most difficult to draw precisely because we are so intimately familiar with them. If your lines are off just a little, the picture will look funny. You might get away with that drawing a tree, but not when drawing a human.
Honestly, this is a stress-free task that is easy to understand but hard to do. It requires me to focus so I won’t be thinking about multiple house chores that I need to finish for the rest of the day or how to pay next month’s rent. It’s a different type of thought to those that bounce around my minds in modern life, and it feels very healthy to give my mind this break.
