Pencil drawings refer to artwork created using a pencil, which is typically a graphite stick. The artist uses different grades and types of pencils to create various shading techniques, from light hatching lines for lighter areas to darker marks for shadowed regions. Pencil drawings can range in complexity from simple sketches to highly detailed works of art. They are often used as preliminary studies or final pieces, and can be combined with other mediums such as watercolor or charcoal.
