Here is how I started:

This is a 4 layer cake- the first 3 layers are chocolate banana cake with banana flavored ganache (6 inch round) and the top layer is half of a ball cake, just plain butter/yellow cake.
I started to carve out the front...

Then I dirty frosted w/ the swiss buttercream I am so fond of :) (thank you Zingerman's!)

And then spent a ridiculous amount of time getting the fondant navy blue. Seriously, it took forever. That is my least favorite part- dying the fondant and kneading. This is what it looks like rolled out...

I think that's about it for tonight, more in the a.m. :)
