Nice concept...
But this had the potential to be much funnier than it actually was, the song was not too great, there were no voices at all, and the drawing and animation were like 10 year old quality. I'm not trying to be harsh here but just honest. On the positive note, your story and humor were alright, I liked how the general sperm had a cigar in his "mouth" but I think more character could have been given to the sperm in general.
