With Shot 6, The Screaming Monkey, I did go in and add animation of the mouth opening as it screams. The added animation did help the scene.
In this shot the tails are animated along with the strand of toilet paper and the hand of the reaching monkey bends at the wrist. I think I am going to go in and fully animate the crowd of monkeys scrabbling for the TP. I suspect that adding ZOE Depth to the background could also help the scene.
Fully animating this scene will be a real challenge so it will be sharing the animation as it is done.
