Witchy Babysitter Piper

In chapter six of The Babysitter, Piper is revealed to be a WITCH (well, we already knew that, but the twins and their brother didn't; dramatic irony). She is described thusly:

In the master bedroom, Piper had pulled the shades and curtains tightly to block out the last of the evening sun. In the makeshift darkness, candles were placed around the room, flickering silently. Piper was levitating, legs crossed, two feet above the Wastefelds’ queen-sized bed. Her eyes were closed, and every now and then a shiny silver triangle placed on the perfect center of her forehead* would glint with reflected candle light.

They arrived just in time to catch Piper levitating before she dropped down onto the bed. Her eyes flew open. They were glowing an intense yellow, no pupils.
“Surprise,” she growled in a deep voice.  
Jessica shrieked and stumbled backwards into her twin, who yelped. Steven was stuttering in panic. “S-she was floating!”
Elizabeth’s mind was racing. What had she just seen? Had Piper really been levitating? She refused to think about what this could mean. It was too bizarre.

So I made an image of that, with Artbreeder & GIMP (because it's fun)

looking happy in this image, because on Artbreeder if you have a photorealistic image and try to make it more angry, it turns into a weird cartoon.

rarr demon eyebrows (did that in GIMP)

 

before/after transformation... I always make her teeth a little pointy because she has "witch teeth" (something I made up, as opposed to "vampire teeth" which would just be pointed canines/ fangs).

*I've said this before, but when I was fifteen I read The Headless Cupid by Zilpha Keatley Snyder, in which the Stanley kids' stepsister Amanda is really into the "occult" and wears a silver triangle on her forehead, calling it her "center of power." So, that was a part of The Babysitter that was really old but stayed in as a nod to my teenage self.
