Just like a building, a drawing is constructed
from the bottom to the top, from the
framework to the finishing touches. Start with
a solid framework before placing your bricks.
Otherwise, everything might just collapse.
To put it more simply, you have to make a sketch
before you start in on the actual drawing.
This is one of the most important rules:
“Start with the global, then go to the details.”
Respecting this rule will allow you to
draw complex things, like the human body.
