Fantasy art style digital painting, a brave fox with a leather harness, holding a detailed sword in its mouth, battling multiple shadowy, demonic figures with glowing red eyes in a mystical, dark forest. The forest floor is covered in moss, ferns, and glowing mushrooms. Magical light particles float through the air, illuminating the scene. Dramatic and intense mood. Deep greens, blues, and dark tones dominate, with accents of glowing cyan and red. Ornate tree roots and vibrant foliage. Cinematic composition.
