The fundamentals of drawing starts with drawing things as you see them. To render a faithful, realistic drawing, you must be able to observe the basic structure of the object, regardless of how complex and obscured by detail it may be.

These basic forms are always based on the cube, the cylinder, a cone or the sphere.

The ability to depict an object literally doesn’t make you and artist, but the ability to draw things as you see them is the first step towards becoming an artist.
