Author's Note: Oddly, I got the idea for this watching groundhogs in a field. If you try to chase one, they just scurry down a nearby hole. And from there it was just a small jump to a nighttime scene with a drow elf escaping with a glowing crystal by leaping down into a deep cave where no one dares follow.
WIP (yep, we're still allowed to have them in illo)
References: elf figure drawn from life (a real live person--sadly, no elves were available to model), gem drawn with the help of this tutorial, and the rest was trial and error.
Thank you for the critique, mystery Worthian!
