The brief asked for a cool and desirable design to go on a plastic cup to be given away by KFC to promote their introduction of Soda Fountains in their restaurants.
My intention was to build the design around the idea of bubbles, which would be made of clear plastic to show the contents of the cup. I ended up using a stream of giant bubbles to further the feeling of movement.
Here is the concept and a sample of part of the design to indicate colours and rendering style.
I've also included a couple of concept roughs that lead me in the direction of the final design.
