Wedding cake butterfly

For this particular wedding cake, I m trying something new by making the topper out of chocolate instead of sugar. It s composed of four layers of vanilla almond sponge soaked in a passion fruit and rum syrup. In between the layers of sponge is a passionfruit crémeux, an exotic compote, a mascarpone coconut whip, and a vanilla Italian meringue buttercream. The roses and the topper are crafted out of 100 white chocolate. What do you think
