There is nothing more daunting than sitting in front of a blank piece of expensive paper, and having to make the first mark. “What if I ruin it?” is something that often creeps into my mind. Many artists like to work through ideas with multiple sketches before they create an illustration, or art of any sort. For the most part I‘m not one of those artists - I prefer to work with an idea or concept. I may start with a few rough sketches so that I have a basis of what my character and setting looks like. However, most of my compositions aren’t preconceived. They used to be - but they aren’t any more.
Some of my best disasters have in fact turned out to be my best learning experiences, and resulted in more exciting art. The secret is - pretend that your intent all along was to create the mistake, I mean masterpiece.
As stated by Bob Ross “We don’t make mistakes, just happy little accidents”. So get out there, and create The Mistake that becomes the masterpiece. If you need inspiration, check out some online groups such as Illustration Age's Illustration Friday and Sketch Dailies.
