I can do a mean giggle

An alien mage witchy character I played a role as in a dream I had late last month. She was at a haunted house attraction deciding how to scare the next few kids, and the one thing I remember saying in her whispery sinister voice was "oh~ I can do a mean giggle..."
I'm still practicing different methods of rendering and painting in my own way, and it's been tricky but fun!
