This is an old sketch based off a dream I had.
Basically there was a serpent that grew plates of silver on its back that gathered around its cave everytime it shed its skin. It also never had to worry about food because of all the travelers who passed and saw the silver glinting in the darkness and wandered in with expectations of riches and instead ended up being the serpents meal.
I changed the idea a bit though after drawing it, there was one girl who would bring the serpent food and with its hunger sated, she was free to collect the flakes of precious metal.
Yeah thats about it
