Digital illustration, whimsical, playful. A cartoon blue whale with a white underbelly and a gray back leaps out of the water, its mouth open as if singing. The whale's tail is raised in the air, and it is surrounded by a splash of water. Above the whale, a seagull flies, adding to the marine theme. The background is a soft, light blue, suggesting a calm sea. The image is drawn in a cartoon style with bold outlines and a limited color palette.
