Beatles' Yellow Submarine Wedding Cake

I made this cake at the beginning of the month for my cousin's wedding. She and her hubby met due to their mutual love of the Beatles! The cake itself was strawberry vanilla, coloured in multiple colours and poured into the pan in sequence, so when cut it would look a bit like tie dye. The frosting was a simple white buttercream, then marshmallow fondant, and the characters are all colour flow. The only inedible part is the topper, which I made from oven-bake clay, so that they would be able to have it as a keepsake for years to come. A sweet cake to kick off life for a sweet couple! :)
