Not to be an ass but OP never said anything about modeling chocolate over rkt or whatnot. Even thought it is presented as something similar " 5 feet tall cake ". Anyways.
To me it looks like one of those " Barbie doll cake " , a base in cake and you shove a plastic figure on top. Just bigger.
Pyro, I was just about to mention that. I hit refresh and you had made the same comment. :)
I didn't gather from OP's remarks that they were trying to pass the ENTIRE cake off as edible. It's clearly a mannequin. I just thought the OP was simply proud to have finally done it, whether it's a life size wondermold or not....
