"Imagine a circular design for a t-shirt featuring a 2D illustration of an ogre and a dragon. The illustration should portray a grim and intense clash between the ogre and the dragon, with both creatures exuding menace and aggression. The lighting should be harsh, casting deep shadows and emphasizing the ferocity of the confrontation. The background should be engulfed in darkness, heightening the sense of danger and chaos. Utilize a monochromatic palette with dark, desaturated tones to create a foreboding atmosphere. Ensure the output is compatible with Cartoon--v 5.1, stylized to 500, and in an aspect ratio of 3:4
