I don't do layering a whole ton but here's some descriptions of ones I have done.

Splatter Comedy, Formula SGHAN3: Birthday Cake, Snow Bunny '08, Pop! - A cinnamon cake left out in a forest and covered in snow

Dead Leaves and Coffee Beans, The Kingdom of Sweets, Peppermint Cream Cupcake, Do You Like Clowns? - The Witch's house from Hansel and Gretel in the fall after she added fresh peppermints and gumdrops
