Your cake looked great especially since you were a fondant newbie!! I was a fondant newbie too but there is a great website with a marshmallow fondant recipe (easier to make and tastes better in my opinion) and lots of good instructions on how to apply the fondant so that it looks like a cake from a bakery! Just type in marshmallow fondant into your search engine and you should be able to find it. I think it was called Fondant 101- marshmallow fondant.
I had to make a three tier cake for a relative's anniversary party and this website was so great! The best tip was to make sure you don't get any wrinkles you have to put the cake on a cake board that is the exact size of the cake. Put the cake board on a can or something smaller than the cake board (something stable) so that when you put the fondant on the wrinkles hang down below the cake, then cut the fondant. You'll get a wrinkle free cake every time! My cake turned out beautifully because of the great tips and instructions. Lots of pics sure helped. Why learn by trial and error when you can learn from someone else's mistakes!
Your cake looked great and I'm sure the next one will be even better!
