Last Week’s Monster Mash Drawing Challenge had users draw monster parties with PicsArt Drawing Tools, and these time-lapse videos show you some of last week’s scariest drawings being drawn live. 

Users created these videos with PicsArt’s  video export feature, and each one gives you insight into the drawing techniques of the artist behind it. If nothing else, it’s always fun and fascinating to watch a drawing slowly emerge before your eyes.
