Happy New Year To All Of You!

I need your help. I am doing a cake for a set of twins(women) that will be turning 30.
The cake is a full sheet witha 3D the yin-yang symbol ( have attached)
Does anyone have any ideas of what else could be put on the cake with this symbol.
Oh did I mention instead of the symbol being black & white, it will be rose & turquoise..

Thank You for your ideas...

On the sheet cake ( if iced white) maybe you can have rose and turquoise fondant circles on the sides to match the circles in the symbols; do reverse shell borders on the sheet cake (I think this border is very feminine) alternating the colors you're using or do them in white since the symbols and circles on sides will have the colors. If you have the tappits funky or script letters or have time to order them place there names (one rose one turquoise) on top of sheet cake (if you have room) or on the cake board. I think this will give you that complete look you're looking for. Hope this helps.
