I made this cake for my son's 5th birthday. It is my 2nd cake I have done. The first one is in my photos. Buildings, signal, and word splats made with cookies and royal icing. Not real happy with how they turned out, but not willing to take the time to do it again. =) They are supported with toothpicks and extra icing. covered in buttercream. I tried to get it as smooth as possible but it wasn't working for me so I gave up.
