Rainbow Adventure on the Ocean Floor

This personal project was born as a submission for the #cspcontest43 organized by Clip Studio Paint.
The theme was to create a fantasy creature, so my goal was to come up with something intriguing that fused together creatures who belonged to totally different worlds. Thus the "Black sea unicorn devil" was born, as both creatures shared something, a light source on their head! With this magical horn he can illuminate a path while adventuring on the dark ocean floor.
