Magic Tricks

The artwork of the cards is pretty much what you'd expect from the cover of the book shown. That's fixable. I can always make my own cards. However, the final effect is that three caterpillars are supposed to turn into butterflies, but the butterflies are all missing from the cards, only to reveal that one of the butterflies is on the spectator.

So, what happened to the other two butterflies? As a story, it leaves you hanging. It would be much stronger if you could show two butterfly cards and then the third card has a missing butterfly (set up expectations, and then the reveal).
