Robot Groom's cake

This is a groom's cake I made for a wedding today (wedding cake above). This is my first standing cake ever, and the height of this cake was about 16". The legs are made of fondant covered rice krispy treats and so are the arms. The head and body are chocolate cake with chocolate frosting. I really wish I had an airbrush for this cake because the silver didn't paint on very nicely. This cake is cute, but definitely not one of my best (but I did try my best). The cake was based off of a picture of a key-chain.
