An art group I'm in on Facebook often posts drawing challenges. I decided I wanted to partake in a few of them.

This one's challenge was to draw your own interpretation of the Powerpuff Girls (or draw in the style).
After doodling them a little in my sketchbook, I came up with this.

They've got weapons instead of superpowers, and probably are just regular little girls.
Maybe someone killed the Professor and now they avenge him by taking down crime in the city. idk
