I think the greatest challenge in storyboards is balancing information and speed. I tried to develop a style that is flexible and allows me to be fast and yet provide as many ideas or answers as possible in terms of framing, composition, body language, lights...all the things that I'd ususally put in a comic's panel. It's very different from what I do in a book, where I can take all the time I want and fill every panel with details.
I loved this story so much I wish I could have done one!
