Concept - Hades I Picture

This concept is for the first school project.
We had to choose a subject (about mythology) and make an illustration about it.
I started from the lowest target, choosing the myth of Orpheus and Eurydice: the first character of the series was (clearly) Hades, who, being a subterrean deity, is depicted as a mole.
Hope it works, considering it's practically the first time I'm supposed to draw for little kids.
