First off I want to say that this is one of the best displays of craftsmanship with fondant I have seen! They really function together as a set, and I like how they all tie together. The two green cupcakes really knock my socks off! I'm happy this was inspired not only by the movie, but the books as well. Your color pallet is excellent, and the reoccurring flowers were a nice touch.
One of the only things I could be knit picky about is the cheshire cat cupcake. He seems just a tad flat and unrelated to the group. (Mind you, this is me really stretching to find something wrong.) I would have liked to see some of the more three dimensional aspects like in the other cupcakes. Also he seems a little disjointed because all the other cupcakes have the ruffle edges. Alone he's a wonderful work, but I don't feel he's adding a lot to the entire set.
Anyways, wonder, excellent, astounding, amazing! You are a real gift to DA!
