It seems to me that maybe the customer had an idea in mind and I’m wondering if it was achieved? A white iced cake, with a tan fondant drape, calla lilies with blue centers and no leaves. WOW. I would suggest always adding leaves to a cake with flowers, because it just looks better. You can see the icing mound on the top of the cake where the flowers were placed which would have been hidden by the leaves. In addition I would also soften the edges of my flowers, theses flowers seem to look a bit to straight.
