Charle's Skateboard Cake

I made the cake using a 9x13 pan and a round pan. I cut the round in 2 halves and put them at each end of the 9x13. I frosted it with white buttercream, then used the airbrush to paint it. I tried to figure out a way to prop it so I could put the wheels (mini donuts) underneath, but it was too much of a pain, so they ended up on the sides.
