Star Wars cake

Darth Vader and Yoda from the trilogy Star Wars. I have to confess I haven’t seen the complete films, so when I heard that little Kjell was fascinated about Star Wars and he wanted to have a cake for his 4th birthday with lightsabers, Darth Vader en Yoda, I didn't have a clue who they were ?!!!
 Coincidentally, It was on television that week, so took a look at it and I just adore the little green master Yoda and all the galaxy features.
This is a chocolate cake filled with dulce de leche and chocolate buttercream.
