插画设计：女孩与鲸共游

Dreamy illustration of a small girl swimming beside a colossal gentle whale in the deep ocean, the whale's enormous body curving gracefully with tiny barnacles, the girl reaching out to touch its fin, streams of sunlight piercing from the surface above in volumetric rays, schools of tiny glowing fish and rising bubbles, trailing seafoam and plankton sparkling, deep blue-to-teal gradient water, soft painterly style with delicate light effects, both figures silhouetted against the light, overwhelming scale contrast and tenderness, palette of indigo, cerulean, phosphorescent green and soft gold, wonder-filled storybook atmosphere, high resolution, 4k
