My Little Pony birthday cake

Both cakes are 9" rounds that are torted and filled. One is White Almond and the other chocolate. Both are crumb coated and ice in buttercream (white cake in almond buttercream, chocolate in vanilla buttercream). The rainbow is made from a 50/50 mixture of fondant and gum paste. The birthday girl requested a RKT heart which sits betgween the two cakes. The pony's are toys the birthday girl got to keep.
