Next, choose one element in the illustration and replace it with its opposite. I chose the witch and replaced her with Glinda, The Good Witch of the North. "Opposite" is open to interpretation. For example, Dorothy would be another possibility.
Next, choose a different element from the original drawing and reverse it. I chose melting and replaced it with freezing. Here the Wicked Witch is trapped in ice. When I drew it, I was thinking about the end of one of the Christopher Reeve Superman movies where the villains get trapped inside some type of mirror or glass (only to be released in a subsequent movie). Another "opposite" here could be evaporating.
