Improv art is a form of art invented by A. Otterness in late 2004. Improv-art is usually used with the medium ink and metal brush on thick watercolor paper. You dip your metal brush into your ink and you make up your painting as you go. You have no rough draft, no pre-drawing, no tracing; just let your immagination flow through your metal brush, and into the ink that stains the paper.
A. Otterness has almost 45 individual ink paintings, and hundreds of marker and watercolor drawings and paintings.
