Really love this as an image even without knowing the idea behind it...maybe have some more abstract things happening as well coming in and out of the head, to complete the image and really put this one over the insanity awesomeness edge?
This is a really strong image as FRICKINAWESOME said, but I think I would like it more if it was hand drawn and if he had a more virile mustache. I mean it is Nietzsche. His 'stache was HUGE. Just my opinion =)
