The feelings that came to mind before I noticed him were:
I don't like the Monk. He doesn't look like he belongs there, unnatural... maybe its just the way he is posing. It could be that he's the moral of the story though. He seems like a modern day kid, dropped off in some ancient ruins, completely bewildered and lost (maybe wondering if he hit his head and is dreaming)
Is the general theme of the songs on the album something that would maybe be described by: Lost, Confused, Out of contact with reality... ?
