when i was a child, i heard this popular folktale, that some ghoul would kidnap little children who still play outside after sunset. they would take the kid and hide them on trees for days. legend has it, when people found them, these kids usually couldn't speak properly for some time as a shock consequences. some even gets mentally disturbed. for me back then, the story was enough to make my eyes gaze upward on trees if i was still outside at night.. :D
this is probably the darkest illo i've ever made..
