Hidden Hogwarts wedding cake

We made this half and half Hogwarts castle wedding cake for a wedding of one of our regular customers. From one side it looks like a traditional wedding cake with drop royal icing but when you turn the cake around there is a hidden Hogwarts side to the cake. Everything is edible on the cake other than the hand sculpted topper that includes Hagrid's motorbike and side car and the bride and groom.
