Drawing is a form of visual art in which a person uses various drawing instruments to mark paper or another two-dimensional medium. Instruments include graphite pencils, pen and ink, various kinds of paints, inked brushes, colored pencils, crayons, charcoal, chalk, pastels, various kinds of erasers, markers, styluses, and various metals (such as silverpoint). Digital drawing is the act of using a computer to draw. Common methods of digital drawing include a stylus or finger on a touchscreen device, stylus- or finger-to-touchpad, or in some cases, a mouse.
A license (American English) or licence (British English) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit).
A license can be granted by a party to another party as an element of an agreement between those parties. A shorthand definition of a license is “an authorization to use licensed material.”
In particular, a license may be issued by authorities, to allow an activity that would otherwise be forbidden.
