Princess Barbie Cake

This is my first Barbie cake done in a cake decorating class. Weighs about 1.6kg, made of sponge cake and frost with buttercream. Started to decortate this at 10.30am and finish it at about 3.30pm and of course there was an hour lunch break. At the end of it, I've got to bring it home. My children were excited when they saw the cake. Too pretty to cut it, maybe I'll wait till tomorrow...
