Cars Birthdaycake

My son Anton turned 5 this past saturday and he wanted a Cars cake(Lightning Mc Queen) with chocolatefillings. Unfortunatly I wasnt superhappy with the result....managed to get som kind of airbubble when putting on sugarpaste on the cake,so it got all bubbly on top and the car itself was harder then i had expected. But my son was happy with it,and that was the whole point! ;)
Yellow spongecake. Filled with Dumle ganache and dark chocolate ganache
