Many of my stories and character development begins from free association. Free association is the process whereby I sit and draw continuously whatever comes to mind. There is no planning or pre-thought on what I'm going to draw. I shut off all my self-editing and just go with whatever idea springs forward. This is a great process for establishing character development and possible story adaptation. Sometimes colour is added but mostly pencil is the medium of preference.
There are no connections between the drawings. It's non-sequitor logic. It's strictly sub-conscious in nature. The wonderful thing about free-association is the ability to take one aspect of the drawing and further revise the drawing into something more lucid and tangible. In all of theses drawings lurks the potential for a character that tells a story either through the spontaneity of their expression or their aesthetic appeal.
