I have always likened this piece as a metaphor for our final journey to the afterlife.
The ageing gentleman's arm and his time piece are the main subjects conveying this theme. His hidden facial features are illuminated by a 'bright light' - a lucky nod to the old saying.
The subject is otherwise surrounded by darkness in a hearse like vehicle, driven by an anonymous figure...
It's all quite on the nose, but this candid photo represents a plethora of emotions and that is exactly what makes photography such an exciting creative outlet to me.
