Short-hands, such as that Disney and comic book artsists use, are not the truth itself.
The initiative behind them, however, are fundamental understandings of the truth.
Thus they can make very good pointers along the search for a good way to approach drawing in general.
Short-hands can be viewed as a double-edge blade. On one hand, they, being able to render certain things with much simpler strokes and structure, means they are the embodiment of certain essence of natural order. On the other hand, because they have often been simplified, looking at them for reference can involve the risk of memorizing flat impressions without further understanding of nature's true form.
