This was made for my cousin's 16th Birthday. It is all cake with the wheels made from RKT. Everything except the wheel axels is edible. This is my most recent cake, 1st carved 3d and the 4th cake I have ever decorated as I am a total newbie to this. Any feedback would be greatly appreciated as I am self taught. I think that I need a scalpel or exacto knife to get cleaner cuts on the fondant shapes as these were doen with a regular kitchen knife.
