In the end I created all the characters and put all the visuals and animation together in about 10 months. It's 38 minutes long and it nearly killed me, literally. In the final stretch I pulled an all-nighter, working for nearly 24 hours straight. I finished and delivered the last scene with Moses parting the red sea and had hardly a minute to spare. I almost ran off the road from lack of sleep when driving to deliver the final renders.
It was hard, and I learned a lot. I'm very excited to start on the next one. I learned how to be a better animator and I've overcome all of the technical obstacles so I can spend less time on problems and more time on being creative.
Here are some screenshots and video.
