My biggest cake yet!!

My cousin just got married and I wanted to make them a really special wedding gift and here it is! This is my largest cake to date and I love the way it turned out. It was almost 3ft tall!! The flavors of the cake, starting from the bottom tier, are red velvet, dulce de leche with a caramel buttercream, white cake with chocolate hazelnut cream and the top two are white cake with vanilla buttercream.
