Street painting initially requires a lot of courage. Few artists are immediately comfortable sharing their creative process; it is intimidating to them. What I have found is that the process results in a catharsis. The artist learns that the public does not actually understand the process well enough to be critical, and is truly fascinated by the creative process, even if it is imperfect. It is a great liberation to learn this. That being said, street painting for tips was initially a survival skill. It was immensely difficult, but the rewards have been proportional to the effort.
