Good Idea!
*Edit*
Yeah, I was THIS excited that I made an entry within a few hours of the contest being posted, lol. I'm going to be kicking myself in 3 weeks waiting.
I used Ness's maker PURRRFECTION for the outfit, but everything else was Google or myself.
La Llorona is rougly translated The Weeping Woman. The story goes that she had several naughty children who drove her insane. She then drowned them in a river and mourned their death for all eternity. As she was insane from naughty children she began haunting naughty children everywhere, and the only thing you have to do to keep her away is to be good.
When children are bad the parents threaten with La Llorona and some go to the extent of having someone moan in the darkness of night when children are naughty. My family took this story even further, but you can read more on that
here.
