Drawing, the art or technique of producing images on a surface, usually paper, by means of marks, usually of ink, graphite, chalk, charcoal, or crayon.

Painting is the practice of applying paint, pigment, color or other medium to a solid surface (support base). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. The final work is also called a painting.
Acrylics, watercolor and oil paintings on canvas, wood, and paper are for sale.
If you hear a voice within you say "You cannot paint," then by all means paint, and that voice will be silenced.
Vincent Van Gogh
