Meanwhile I was making mood boards and concept design sheets for the characters:
To make these sheets, I gathered lots of images online, from illustrations to photographs and three dimensional work. Then I cut them up and stuck them back together - digital collage. I used this stage to help me get a sense of the character's personalities and how I could express each one through physical appearance. And although the puppets ended up looking very different from the above designs, it really helped me to work through my ideas and either eliminate thoughts or bring them forwards for further development.
