Ombre Birthday Cake

I made this chocolate ombre cake with swiss buttercream icing for my friend Iris's birthday ! I probably should have used a different tip to write Happy 22 but I couldn't find it :(  I broke two mixers making the icing for this cake  (crappy Hello Kitty ones) so it wasn't as well blended as it should have been. I also did not have a 1M tip so my swirls weren't as big and cool but I was pleased with the ombre effect (only wish I had done just one more darker/est row on the bottom and shifted everything up so there was less white). All in all success, and the crowd loved it.
