Generate a close-up image of a demon on a rock with a dark hangar background, incorporating dreamwave and golden ratio elements. The demon should have shining claws, be in an action pose, and have fiery wings. Use ultraviolet photography and a spotlight effect. Ensure the image is highly detailed, lifelike, and in 4k resolution. The style should be reminiscent of Dominic Lefevre, Wlop, Stanley Artgerm Lau, Ruan Jia, and Fenghua Zhong. The atmosphere should be dramatic, surreal, and crepuscular.
