I entered this cake into a cake decorating contest for our city. Yes, this is the second R2D2 cake I've done, but I didn't want to break new ground in a timed competition. It won second place. I am thrilled. There was no way it could have beat the first place cake. I'll see if I can find a picture of the cake that won first and post it on here too.
25 of the 200 points went to the flavor of the cake so mine was (from bottom to top) Chocolate cake, chocolate ganache, butterscotch cake, Salted Caramel filling, White cake.
Here's a picture of the cake that won first place:
