From the bigger cake in earlier photo/description, I removed the bottom tier (I actually won't need it for this weekend, as it is too big), and re-arranged the 6 and 4 inch tiers into a smaller but more ornamented cake.
Buttercream, fondant flowers, candy sugar accents. Inside is chocolate with Ghirardelli chocolate filling (middle), and butter-vanilla white with strawberry/cream-cheese filling (top).
