Some of the most challenging things to draw include facial expressions, foreshortening of the human body, drapery folds, drawings based on your ideas instead of a direct reference, hands, movement, and gestures.

Drawing is hard because our brains interpret anything we see as a whole, and our eyes don’t create an authentic image of what we draw. Drawing becomes even more difficult because we tend to draw things as we know them, but not as they are. Learning to see is hard, so drawing is hard.
