Detailed full body concept art illustration inspired by plague style oil painting on canvas, featuring a little viking warrior girl in full intricate clothing, set in a biomutant dystopian world. The artwork should focus on micro detail and be rendered with an octane finish in 4K. The piece will capture a unique blend of abstraction and realism, with a hint of cartoonish elements. The character is depicted with a single head, proper anatomy, and balanced proportions, eliminating any deformities or disfigurements. The colors should be vivid yet harmonious, with a soft dark focus to enhance the mood. Ensure the composition is clear, avoiding any blurriness or unwanted marks. The warrior girl's features and clothing will be richly detailed, emphasizing her Viking heritage while incorporating imaginative, mutated elements that fit the dystopian theme.
