His character will be doing free running/parkour with the ability to emit graffiti from his footsteps. The main character-teenager-reaches his stop and looses focus of his imagination, causing the free runner to kill himself during his last stunt.
Concept: Inability to escape from reality
How: illustrating is main character's method of escaping. His inability to draw/translate ideas hinders his escape.
inability to devote full attention to imagination/drawings
Connection btw Graffiti & Free Running:
Graffiti writers and free runners use the environment to reach seemingly unreachable locations.
