Imagine a circular design for a t-shirt featuring a 2D illustration of a dragon. The illustration should depict a majestic and fearsome dragon in flight, with intricate details in its scales, wings, and facial features. The lighting should be epic, casting dramatic shadows and highlighting the dragon's power and grandeur. The background should be dark, with hints of fiery orange or red to create a sense of danger and intensity. Utilize a monochromatic palette with subtle color accents to enhance the mood. Ensure the output is compatible with Cartoon--v 5.1, stylized to 500, and in an aspect ratio of 3:4.
