Quickly become better at drawing—without burning out—by using my workbook.
participated in ACM programming contests with two other programmers when I was younger. Each would select an assignment to code, think of an approach, discuss it with another team member, and implement it. If the code didn’t work, and the team member could not figure out why, it was handed to the person it was discussed with.
The amazing thing was that the other team member often spotted the mistake immediately!
We all make different mistakes. This is true for drawing, too. You can spot mistakes in someone else’s drawing, and the other can spot them in yours.
Next time you see a drawing where something is off, consider using it for reference, drawing your version with the mistake fixed. (And do not show it to anyone!)
