Digital painting of an enormous snail whale swimming slowly through a sea of clouds above the mountains, extreme wide shot from the side. It has the long smooth body and wide fins of a blue whale, pale blue with soft spots, and on its back sits a giant spiral snail shell like a lighthouse, with tiny round glowing windows set along the spiral and a small door at its base. Two long soft eye stalks rise from its head, each ending in a glowing pale yellow eye. Small birds and fish swim together around it through the clouds, and its slime trail glitters behind it like a river of light. The sky above is deep blue with the first stars, while the clouds below glow peach and pink. The palette is deep blue and periwinkle with glowing pale yellow, peach and soft pink. Loose painterly brush strokes, glossy highlights on the shell, soft glow on the windows and a calm, wondrous mood.
