I used these directions as a starting point for this crown cake…

However, I did not use royal icing for my crown, I used white candy melts. (The design of the crown needs to be simpler, because you cannot get as fine a line with the candy melts.) And I added small jelly beans (jelly belly type) as “jewels”.

The name plaque and Disney princess pictures are frozen buttercream transfers (directions here: http://www.cakecentral.com/article12-How-To-Create-a-Frozen-Buttercream-Transfer.html), but I wasn’t pleased with how they turned out.
