This Video is a condensed demonstration on how I illustrate a bike. I first start with a rough sketch of the bike working from photo references of the actual motorcycle. I work out all my proportions and basic shapes on the rough and them place it under a piece of tracing paper called vellum. The final drawing is done with a black marker and fine tipped technical pen. Most of it is drawn freehand with an occasional use of a straight edge or curved guide. Forty minutes of drawing has been edited down to 7 minutes.
This is Bike HDFB-001 colored in watercolor.
