A medium shot from a low-angle perspective features a fierce dragon girl standing centrally in a medieval fantasy castle courtyard. She is a tall, curvy woman with short red hair,golden eyes, and two short straight horns growing upward from her head, her expression stern and determined. She is clad in tight green sleeveless plate armor with high-leg styling and a matching green front drape; her right hand firmly grips a decorated spear with intricate red patterns etched into the blade, while a sword remains sheathed at her left hip. The setting is a wide stone courtyard crafted from weathered grey masonry, surrounded by towering castle walls and gothic arches under the warm glow of afternoon sunlight. The visual style is a high-quality anime illustration with a heroic atmosphere, characterized by a rich color palette of deep greens and reds, sharp linework, and soft environmental shadows that emphasize the depth of the scene.
