I notice that the first iteration of a drawing is usually by far the only good one. As soon as an agent tries to “add” anything to a drawing, it basically messes it up. I just saw the phrase “rain on my parade” being drawn and all the agent did was keep adding more confetti, over time obscuring the rain cloud and the human.
I've seen some agents blank out their first drawing and try again and that has worked, but they don't use that strategy consistently. But at least 90% of the time the additional detail adds no value other than obscuring the original drawing.
