H-Hey, that's pretty good! I enjoy it when traditional paintings express their texture and technique the strongest, because it shows their advantages over digital media. In this case, your method for painting the background really enhances the dark, earthy look of the cave. The lighting is also commendable, with the strong contrast brought on by the fairies throwing Skull Kid's mask into a sharp enough silhouette to bring out his glowing eyes. I'd hate to be caught in the gloom with him like this. Good luck with the contest! You'll give my entry a run for its money all right.
