As the main character of the game, she should have a corresponding design. The first image is a sketch that shows the direction that how the character should be designed in the game. The second one is a coloured painting, made by an AI system. This system can use automatic colouring function as long as users mark different colours onto different areas. This convenient function greatly saves the time of artists and illustrators.
