Apply Squash and stretch
As one of the 12 principles of animation, squash and stretch is a useful technique in giving your drawing more life and energy. In animation the use of squash is often used as anticipation for a broader action: the stretch. The same can be done in a single drawing. An action can still be read in a still image. A stretched pose acts as a moment in time when the character is creating their broadest action, while a squash in a drawing reflects tension.
