The elements of Drama have been described by John O'Toole and Brad Haseman to identify what is needed to create and perform a story for an audience. Any given theatre performance features all of these elements working together to focus the dramatic action and create dramatic meaning.

(Clausen, M. Centre Stage)

To tell a story on stage, you definitely need to work on your acting (refine your expressive skills), but you also need to be able to think like a director or playwright in order to effectively construct your performance. Understanding the elements of Drama will help you to consider what your performance needs to make it more engaging, more exciting and more meaningful for your audience.
