You did a great job with the definition here, I liked the statistics that you included, the cute joke about cereal, and your definition of crop circles. All of those really tied together well! I felt that the plane guy was a little random, I think you could put in some sort of crop circle statistic there that would still be visually significant. If you want to keep him, I would suggest taking out the white background.
I liked how everything made its own crop circle, that was a really nice touch.
