Combined Birthday Cake

I made this for friends of mine who have four children, and they do a combined birthday. The girls all started home schooling this year, and their son loves Lightning McQueen. Scissors and ruler made from chocolate, pencils and pencil holder made from gumpaste, car made from RKT and covered in fondant, paper made from 50/50 gumpaste & fondant, writing w/edible pens. I waited too long to add it to the cake which caused it to crack! Road made from chocolate fondant colored black.
