Shark And Goldfish Birthday Cake

I made this cake for a little boy turning 4. The cake matches the invitation. Mom wanted 4 goldfish on the cake with a candle in each of the goldfishes mouths. I took the picture before the candles were put on the cake though. The icing is buttercream. The shark and goldfish are made with marshmellow fondant. To get the different shades of blue I used an air brush.
a very neatly done cake, how did u do the shades? good job!
This adorable, I really like the goldfish. How did you make them?
