Create a slim male human character, with a psychotic and frightening expression

Create a slim male human character, with a psychotic and frightening expression. He is surrounded by a swarm of small insects, reflecting your connection to nature. Your skin is light brown, and he has long black hair, that cover part of your face, giving it a mysterious air. He wears black clothes, complemented by a long overcoat, all in a fantasy medieval style, with bright colors that contrast with its dark presence. The image in cartoon style
