Topsy Turvy Graduation Cake

This is my first Topsy Turvy cake. It was really scary getting started on it, but I'm pretty happy with how it turned out. I made it for my Nephew, Brian's high school graduation party. The grad cap, diploma, skateboards, and all the other decorations are made with marshmallow fondant. It's yellow cake, with cookies & cream filling. (I'm hooked on that stuff now). :)
