I produced storyboard first, and in collaboration with the client, we modified it for greater clarity. It then moved on to an animatic, and ultimately a simple animation. The brief was for a simple rough drawn style, and so I kept close to the initial sketches from the storyboard.
I refined it to a slightly higher fidelity, however the project lost funding and fell through. Therefor this is as high fidelity as it went.
I enjoyed work, and the process went well, however the big lesson here is that there is no deal that includes proof of concept before payment.
