Some of the do´s and don´t are really a bit stupid.
I love the howtothinkwhenyoudraw ones by the Etherington brothers
and they have some of the do´s & don´t too
And I like the approach to learn many ways to draw something,
like the Riley & Loomis method to draw the human body, I learned
them both but both don´t work for what I´m drawing so I invented
my own method which is maybe wrong for some people but works
for me perfectly.
I think about a way to put that into an art tip
