A Promise was made Painting

Another piece from my collection 'The Writing on the Wall'. The message on the wall is 'I will return'. I've painted the figure in the exit in a way to appear he could be leaving or he has just returned. The figure on the ground is clearly unable to leave so easily. As the title depicts 'a promise was made' .has the figure written this message on the wall for when is friend awakes...or has he already returned? Is the figure on the ground begging him to stay but he makes a promise and writes it on the wall to his friend as a constant reminder.? The light will protect the figure on the floor whilst the other has left to get help...or is this light a vision from the figure about to leave for the spirit world? My work is to leave many options for the viewer..I want the viewer to create their own story based on my foundation of a composition and the writing on the wall.
