Unicorn with Rainbow Birthday Cake

Kids LOVE unicorns, and there is no scarcity of unicorn cakes on the internet. My challenge, though, was to make a cake for an ADULT who likes unicorns, rainbows, panda bears and stars. . . Which is all the direction I had. I dont know the cake recipient well, but hope that this cake was not too childish for her. Or maybe at least brought her inner kid out and put a little fun and whimsy into her birthday. :-)

The cake is double chocolate, with chocolate fudge filling and buttercream frosting. The rainbow is licorice and the unicorn, stars and flowers are marshmallow fondant.
