DEMON (Oni). Character Art (Concept)

I drew a Japanese mythology character called Oni. Appearance of that kind of demons may be very different. My oni has red skin, lots of horns from his head, strength and dangerous power.

"Oni are mostly known for their fierce and evil nature manifested in their propensity for murder and cannibalism. They are typically portrayed as hulking figures with one or more horns growing out of their heads. A creature instills fear and danger from their grotesque outward appearance to their wild and strange behaviors and dangerous powers"
