If you had done a project for class, and you went into a store a year latter and were shopping when you see YOUR CEREAL BOX design FROM CLASS, ON THE SHELF? Sure theres is better becasue they are a pro and know how to do everything right. But it's not right to steal other peoples designs.
Sure there are sometimes when two people can come up with the same thing, however, the same colors? same animal?, and same backwards baceball cap????
