Sunshine Birthday Cake

A is 7 tomorrow! He wanted to help with his cake this year, and wanted his cake to look like a sun.
Here is the result.

One chocolate cake with buttercream filling (made by all 3 kids), covered with a layer of white fondant icing and then details added in red, orange and yellow fondant icing.  We deliberately kept the design simple so it should be impossible to tell which bits of the decoration are mine and which are A's.
