I really appreciate the feedback. All I thought to use was my red stargazing flashlight. I've never tried light painting before this attempt other than a few kitchen experiments. Next time I'll do this red light because I like this end result. However I'll absolutely try OTHER colors as well. I had my regular flashlight for example, and could have used that.
I made a video of this in the link below. I think the picture is spooky, so I made a spooky panned video of it with my voice quadrupled and pitch-shifted to sound something Holst's "Neptune," or something...lol
