That's awesome Ash! Go for it - your wedding is about you!!

Cai, friends of ours had a similar cake to the one you like, except the toppers were very funky little skeleton bride and groom. It was exceptionally cool (and yummy too, it was a mudcake)!

Other friends of ours had a sci-fi/anime themed wedding. Nearly everybody dressed up, including the parents of the bride and groom and the celebrant. It was held at Darling Harbour, and I got asked by a Japanese tourist whether it was a sci-fi convention. She was a bit surprised when I told her that it was a wedding. Everyone had so much fun helping the bride and groom celebrate in a way that really reflected them!
