I encourage both fantasy and realism in drawing. Children under the age of eight generally have amazing and unique perspectives on drawing, so I usually coach them by encouraging of what they have already invented and give tips for how to make it even better. Around age nine, children want to draw realistically. From that point, I offer help with perspective, proportion, shading, and composition.
There are many fun drawing exercises that can be used to loosen up the fear of making mistakes, including: scribble drawing, timed drawings, still life studies, left hand/ right hand drawing, negative space drawings and contour drawing.
I use the following mediums: pencil, colored pencil, charcoal, watercolor pencil, pen and pastels.
