Zebras don't cross the river is more like kids, who leave their parents and don't care about their hard work while raising them, shouldn't just pop out of the blue just for the sake of it and not because they mean it. Specially after the parent is at the very verge of getting over them. River is metaphorically the space the parent has to himself now, and the son DARE not cross it... :P
About the voice overs...yes, they should have been better, i was lagging on with the submission of the project so just rushed through it... i'll do a better one next time.
thanks for the appreciation. :)
