I make a lot of rough sketches to explore new ideas or to prepare a design for a new painting. You won't see much of these displayed in the galaxy!
Sometimes I start a drawing that I like and may work on it more to flesh it out. If I really like it, then I might show it here. I like to make color drawings on black paper. When I draw on white paper, I might use a variety of mediums, such as pencil, color pen and possibly some light use of paint or color ink.
Drawings on paper are as much original art as a painting on canvas. Just as with a painting, an original drawing has far more character than a print copy.
