As we wrote a rough script for the story we decided that the first half part of the documentary would be about the silk goddess who discovered the silk worms and made silk cloth from the silk they produced. So I did a mood board for the production of the silk in the past for further references when animating the woven machine and producing the backgrounds.
I did a few sketches with and without colors, with different materials such as marker pens and water colors, to test out the most suitable method that we should use for the character. We all agreed on water color as it create the texture of a informative historical story, and delicately shows the oriental style at the same time. So below are the sketches I did and a character guide of the 3 side views for the final design of the character that we are going to use in the animation.
I was looking at references and inspirations from animation short films that was done by other people, I came across Happy Time and The Traveler, where the first one was a pure inspiration of watercolor animation, that I found very suitable for a documentary that involves history. The Traveler is obvious an animated short of a combination of watercolor and After Effect animation, the composition of the assets especially.
