Buttercream, Fondant, Ganache, The Passion of Wedding Cakes...

This weekend I have an appointment for my cake tasting...I'm totally overwhelmed.
I have no clue about what I want and even though I've found millions of photos and ideas on-line, I've yet to figure out exactly how to personalize them to fit my specific theme, personality, and event.

The baker (Creative Cakes), ladies if you haven't yet tried Creative Cakes, please let me offer the greatest recommendation. I discovered them while attending a bridal show and noticing women salivating at the table while biting into their samples. My florist came along with me and ate about 7 slices worth of cake, and they were more than happy to give it to her..lol

Either way, I can't imagine what it is I want...

Do I want a fabulous sleek round cake with intricate details and latticework and flavored filling or do I want a Monochromatic square cake with icing pearls and sugar bows and ruffles. Speaking of fillings, do I want raspberry-and-grenache filling, strawberry and cream cheese filling, or rather Grand Marnier buttercream filling...Decisions Decisions

I will be asked to fill out a questionnaire during the tasting highlighting the following, and so I've gotten a head start as of today in thinking about these things beforehand.
I'll be asked to rate:
-Shape (Round, Square, Hexagonal, Architectural (Topsy Turvy), etc)
-Color
-Decoration (Basket weave, Dragées, Piping, Satin bows and ribbons with pulled sugar, Gumpaste, Latticework or scrollwork, or Swiss Dots, and etc.)
-Flavors
-Frosting & Filling (Classic Buttercream, Fondant, Ganache, Royal Icing, Whipped Cream, Marzipan, etc.)

Either way, this seems to be one of the hardest decisions I've had making during this process...I'm at a total loss, I have no idea what I want...I do know however, that TASTE is important, I want my cake to ooze fresh and luscious icing so tasty that it brings a tear to the eye.

I'm open to suggestions, and I'm looking around for ideas...
