A young boy with swords spars with a tall skeleton in a grassy field under a surreal sky, in a cinematic fantasy illustration.

Epic fantasy book cover illustration. A young boy with black wavy hair sparring with short swords in an endless field of tall, wind-swept grass beneath a vast, surreal sky. The boy glows faintly with an ethereal aura, wearing simple leather armor with gold trim, his posture focused and determined. Facing him is Bert, a small goblinoid skeleton with exaggerated features: long arms, hunched posture, sharp teeth, oversized hands. Despite his skeletal form, he moves fluidly like a fighter, not a shambling corpse. Both figures are locked in mid-motion, captured as if in a graceful dance of training rather than deadly combat. The grassland stretches infinitely in every direction, surreal and dreamlike, painted in soft mystical hues of green, silver, and faint blue. Highly detailed, cinematic fantasy illustration with dramatic lighting and painterly textures. See more
