One of my pitfalls as an “artist” is my complete lack of patience. I like drawing and I will take a lot of time getting proportions and angles right, placing objects on the page, getting shapes as close as correct given my meager ability, etc. But then I try to rush the important parts – ink, color, details.
For example, in the first video below, I would look at that drawing and think “Two minutes and I’m done with this!” and that is always the wrong choice. More than seeing how the artists handle their pen or brush, it’s instructional to see how long it takes to get the ink on paper and how delicately and deliberately they work.
