A dark horse rears up, illuminated by a glowing jack-o'-lantern held by its rider, who wears a bright red cape flowing dramatically in the wind. The background is filled with vibrant purples and blues, while eerie fog rolls across the ground. The art style is a bold, stylized painting with strong outlines, vivid colors, and a sense of movement reminiscent of classic horror illustrations. <lora:headless_horseman_v10_rank32_bf16-step03000:1.4>, headless_horseman
