Hi Maia! Your getting some great tips already but I thought I would throw in my thoughts. I do play the in and out game putting it in the fridge in between carving and decorating. Sometimes the freezer for a bit, all depending on where I got room and how the cake is holding up. It is very much so a learning experience, I say start with a easy shape first. My first 3D cake (i think) was the football helmet I did for my husband last year, was a good piece to start with, minimal carving. I will say this, store it in your fridge if you can! I made a really good Captain America shield, which is a really easy cake, not much to it but I had a beautiful detailed curve so it would’n’t look like just a circle cake. Covered it with fondant and left it on my kitchen counter overnight and went to bed. I noticed in the morning the fondant was ripping and pulling, the cake sitting at room temp over night (I live in AK so it’s normally just fine) The curve of the cake couldn’t support the weight of the fondant but I know it would of been fine if I put it in the fridge. Lesson learned. I’m with CorpseQueen, I use a small pairing knife and I want to try a steak knife out now. No matter what you do cut little by little, it’s like cutting hair once you chop it all off it’s gone! Good luck and let us know when you plan on making one!
