Drawing is more personal, as it is a way for the artist to express themselves, while an illustration is more professional and commercial. Illustration is a profession, as publishers and authors often commission them. Drawings can stand alone, whereas illustrations always accompany the text. Renderings are often sketching, or they can be conveyed in two dimensions.
However, you may also use a wide array of tools, including charcoal, colored pencils, pen, and ink. Illustrations are often created as a painting, drawing, or photography. Illustrations are found in books, especially children’s books, and newspapers. Both drawings and illustrations are visual expressions.
The main distinction between drawing and illustration is that drawing is a more personal form of self-expression. In contrast, illustration is a professional venture that has the possibility of commercial importance. Another difference is that drawings can all be separate, and they stand alone, while the illustration is always a creative feature of a book.
Drawings can be anything from a professional blueprint, an outlined figure, or a sketch of someone or something. A drawing is generally done with a pen, pencil, or crayon, and rough sketches are almost always done in pencil. Illustrations, on the other hand, can sometimes be more visually appealing, as they are made with paints, colorful drawings, and photographs.
