Create a high-definition, photorealistic artwork of a Cockroach Knight with a question mark on its chest, inspired by the styles of Kazuo Umezu and Frank Frazetta. The knight should be wearing a white robe with dayglo pink accents and be set against a backdrop that incorporates elements of Iram of the Pillars and Jorogumo. Include a mysterious, featureless stranger in the scene, with a creepy, gothic-inspired aesthetic. The artwork should adhere to the golden ratio and have a psychedelic, overcast tint. Ensure that the piece is highly detailed, with a focus on micro details and lifelike textures. The color palette should be vibrant and cinematic, with a mix of realistic and fantastical elements. The final piece should be reminiscent of the works of Dorothea Tanning, Magali Villeneuve, and Artgerm, with a strong emphasis on anthropology and wonder.
