Create a highly detailed, matte painting- style concept art of a mud monster in the style of Batman comics, with a dark red, slimer- like face and skin. Incorporate the elegant, intricate aesthetic of Alphonse Mucha and the color scheme of Morandi, with a white and gold palette. Set the scene in a dimly lit, dark corridor basement, with sharp focus on the monster's face and skin. Use a bambino pen- inspired line art style and include micro details and shadows. Reference the Teen Titans and Kingpin characters, with a hint of a 'bumbler' persona. The output should be a high- quality, HD image with lifelike details
