I wish I was a duck right now...
I put 5 because I didn't wanted my own appreciation to tamper with other's... Anyway it's more like a subjective and unique experience that anybody can interprete his own way.
Thank you for this piece of art and philosophy.
Ps: I'm very impressed by the variety of moves the duck is able to do, very realistic too, must have taken you a lot of time observing duck's lifes, awesome
