Something about this painting is reminiscent of the way I(and I'm sure many others) would paint my comic-book heroes at around that age, albeit perhaps lacking some of Michelangelo's talents and skills.
This painting makes me feel like the bible was pretty much a comic book to the adolescent Michelangelo, and I like that thought. He later went on to paint the ceiling of a huge temple dedicated to his equivalent of Charles Xavier.
I bet that felt pretty cool for him =)
