Whimsical Anime Cow in a Medieval Castle Hall

An adorable cow drawn in anime style with large sparkly eyes, soft cel-shading, and a cute expression, standing in a grand medieval castle hall. Stone walls, tall arches, flickering torches, heraldic banners, and stained-glass windows casting warm multi-colored light. The cow wears a tiny knight's helmet perched jauntily and a light red scarf, adding whimsy. Dramatic perspective with warm cinematic lighting, pastel-to-earth color palette, atmospheric dust motes, and a slightly misty air. High-detail anime linework, 4k quality.
