Troy's Pre-K graduation cake

Its bittersweet to see the kids growing up. Today was our son's Pre-K graduation, he starts Kindergarten next month but this is a big step. They did a whole cap and gown ceremony with slide shows and video of the kids from throughout the year (He's only been there 3 weeks but they still had plenty of him). After the ceremony was a picnic in the park so I made this cake to go along. Its a marble cake with an Oreo butter cream filling. The little feet under the top cake are 9 boys and 5 girls for the kids in his class ( the girls all have purple toenails).  The graduation cap is cake, the cap board is cardboard covered in Fondant.  The tassel is fondant as well.
