Serenity cake

I tried to recreate a picture of Serenity in cake and candy clay for my brother's birthday. The proportions are a bit off in the back, but otherwise I'm pretty happy.

The cake is chocolate meringue, filled with peanut butter mousse and iced with whipped chocolate ganache. Both the sky and serenity are made from vanilla candy clay. I used white lustre dust for the mettallic finish, and gold in an attempt to give the impression of light reflecting from the glowing engine, unforntunately it doesn't show up in the picture.
