According to How to Draw & Paint, simplify a tough drawing by visually breaking it into parts that consist of basic shapes, such as circles, triangles, squares and rectangles. To draw a Pegasus, begin by sketching the largest part of a Pegasus with an oval or rectangle, and then add details to it, such as wings and hooves, by sketching their basic shapes.
Drawing complex items is simplified by using basic shapes. Quickly sketch a series of rectangles or ovals to represent the general shape of the Pegasus' body and legs. Add triangles to represent wings. This provides an idea of how much space on the paper that the Pegasus takes up and grants a starting point for adding detail.
Defining the size of the drawing at the start allows artists to avoid running out of room before the drawing is finished. How to Draw & Paint states that quickly sketching the basic shapes of different parts of a drawing allows the artist to avoid second-guessing. The brain instinctively picks out the important lines of the image.
Once the rough shapes are on the paper, modify mistakes by erasing misplaced lines, incorporating shading, and adding and removing curves or angles. This creates a sense of dimension and realistic detail in the drawing.
