Luminous kid on doodle whale

A luminous kid sits atop a doodle whale made of filament-like light, relaxed and wonder-struck as it glides above a misty park path at twilight. The whale moves with gentle purpose, leaving a warm amber and pale pink trail that threads through cool cyan haze and deep violet shadows. Low mist hugs the asphalt and grass, softening distant trees and benches while a faint moon glow gives the scene a serene, dreamy mood. The kid and the whale are tactile with a mix of soft radiant filaments and matte park surfaces like damp leaves and worn wood. The closest filaments and the child's face resolve in crisp focus, while middle and background layers dissolve into gentle fog. Frame vertically in a 9:16 portrait crop, tight enough to keep the whale and child central with negative space above to emphasize ascent. Include a cast-iron park bench and a lamplight pool as subtle props to anchor scale. Render in painterly mixed-media with luminous linework, soft blended atmospherics, and a hint of grain for tactile charm. Motion is implied by the trailing glow and a few drifting leaves that follow the whale's wake.
