Last time I write a crowd scene into a script… eech.
Ended up animating them with a simple python script - iterate through the crowd members, make them blink at random intervals, have them all look at target A some time between frames 700-750, back to me, etc etc.
Good job , in any animation if after 5 sec u start to focus on the content and forget that its an animation , then the animation creator has done a good job. And thats what occured to me.
( always happens to me when i look at a pixar movie , first I try to concentrate on The CG part but, then i get carried away by the story and forget to watch out for the CG part)
the reflection on the tablet at 42 sec looks strange
Yup - that’s the big bod’s mouth, d’oh… noticed it too late to change it. C’est la vie 
Glad you liked it - encouraging to hear the story comes across well. Thanks!
