A quick way to re-discover a direction in your artwork is to draw/paint a self-portrait. I know some artist are not into self portraits but it will teach you to see “Your soul” and portray it. It forces you to go beyond your limits and pushes you to the next level. Trust me. It’s not easy! Don’t give up either. The artwork will become your great piece.
When sketching an idea or composition focus on you up close or in a simple composition. Photograph yourself in the same environment about 50 shots. This will force you to push pass the “Normal photograph”. It also teaches you see in a new direction, something that hasn’t been done before.
