Here are a couple iterations of character designs for a game we are making at Intellimedia. The game will be delivered on a giant touch screen and can be played by several children at the same time. These are possibilites for the avatars the children can choose from.
Originally I had designed these amorphic blobs and creatures based on themes from the game. After getting feedback from the team it was decided to take the shapes of the blobs and make them into human superheroes.
