3 Floating Bridal Shower Cakes

This was my very first commission AND my very first time to work with fondant!! For the middle cake I ran into a problem trying to get the fondant to go on smoothly down the sides. I ended up gathering it in the front, hence the flowers to cover my mistake. Someone tell me how to do the fondant right, please! I painted the leaves and pansies with super luster dust. The flowers are royal icing, the leaves buttercream. The top cake was supposed to be quilted. The lines were really faint, though. Help!
