Sand Castle Wedding Cake

This cake was a lot of fun but also a big headache! It was a HUGE cake (28x20) with 5 different kinds of cake/filling. The left side was chocolate w/vanilla, right side was white w/raspberry, top square was white w/chocolate ganache, front towers were yellow w/chocolate ganache and back towers were yellow w/BC. I did this for a good friend of the family's reception. She wanted the cake to look like it was made out of sand on the beach and didn't want it to be too "perfect or pretty," I wasn't extremely happy with it, but the bride and guests loved it, which is what counts. TYFL!!
