Hot Wheels cake for Harrison

Here is my first CCC (cupcake cake). It is made by placing cupcakes close together, then frosting them in a way that makes them stay together in the form that they were placed (similar to grouting tile, i guess), then decorated and stuff. So Harrison turned 4, and had a Hot Wheels themed birthday party at a fancy car place.
The cars were all made out of fondant, using this tutorial http://www.cakejournal.com/archives/how-to-make-a-race-car-cake-topper

Happy Birthday Harrison!!!
