Here is a page from a rough storyboard for an 11 min Pilot we made recently. The whole 11mins were roughed out in 5 days, then the clean up and tweaks took a week (with an over lap so a total of a week and a half). Not the way we prefer to do things but sometimes we have no choice! Helps when you have a good team. I like the drawings as they are but you have to have it all tidy for clients to refer to.
