Teach It Tuesday - followup. June 4, 2013 Rob Teach it Tuesday - followup. I was asked how I hand drew the dirt / dust cloud. I created a layer and using a standard brush with a wide pattern started painting. You can see from the animation that I alternated dark and light with the spray pattern. I would add, remove, add, remove until it felt like it was looking right. As a finishing touch I covered most of it up with a 40% opacity brush with the lighter color.
