What are the 2 types of free hand drawing?

The two types of freehand drawing are observational drawing and imaginative drawing. Observational drawing involves creating images based on direct observation of subjects, such as still life, landscapes, or live models. Imaginative drawing, on the other hand, relies on the artist's creativity and imagination to produce original compositions, often without reference to real-world subjects. Both forms emphasize the artist's skill in rendering shapes, forms, and expressions without the use of measured tools.
