Does anyone have advice for carving these tiers similar to the photo below?

It says, page not found?

Yep, not coming up. I do however have two different pumpkin cakes in my photo pages, one is Cinderella coach and another is a Halloween cake. The smaller pumpkins are done from a pumpkin cake pan, the bigger pumpkin is one I carved using a very cold, near frozen cake. 4 10" round cakes stacked and iced. If this is what you are talking about I'd be glad to help you through it.
