Cake was half strawberry/half chocolate with vanilla buttercream, covered with gray marshmallow fondant. After I used hand tools to 'carve' bark shapes, I airbrushed black lightly along the the deeper cuts and then airbrushed a light coat of brown over the whole cake. Moss at the bottom made from crushed graham crackers covered with 3 different Americolor green gels. Mushrooms, baby and leaves all made from fondant. Cut out a rough circle in the top fondant and replace with a gold fondant disc and drew in the tree rings with brown edible marker. Really happy with how my first airbrushed cake turned out.
