That's a really pretty cake! Even the writing is better than I've seen on a lot of Cake Wrecks. (BTW, if you want to bolster your self-esteem, go check out Cake Wrecks. Every single one of those cakes was professionally made and sold. Then look at the Sunday Sweets posts for inspiration.)

And again, remember that the primary purpose of a cake is to taste good, not to look perfect -- the latter is lagniappe.
