Education, Good-Looking, Well-Animated!
This is extremely impressive considering that you say that you "whipped it up in two days"! I thought it was a great animation, included accurate information, had very good graphics, and even interjected some humor into what some could perceive as a dry topic.
I really have no advice to offer you. For your next production just increase the length, maybe pick a topic more appropriate for Newgrounds (i.e. violent :) ), and you are well on your way to success!
