Boy Chasing Airplane Contrail

Create a vertical 2:3 anime-style summer illustration about departure and chasing a contrail. Show exactly one young boy, around 8–10 years old, seen from behind, running uphill on a sunlit coastal path with his right arm reaching toward the sky. He has messy {argument name="hair color" default="dark brown-black"} hair, a loose short-sleeved white shirt fluttering in the wind, blue shorts, white socks, and sneakers; one foot is lifted mid-stride to convey motion and excitement. The path is a pale stone or concrete walkway bordered by a white wooden fence on the left, lush green plants, and yellow flowers, descending toward a bright seaside town and sparkling ocean. In the sky, include exactly one small white airplane near the upper right, leaving exactly two long sweeping white contrails that curve down toward a huge cumulus cloud mass. Include exactly five small white seabirds scattered in the right half of the sky, and exactly two utility poles on the right side near the coastal houses. The horizon should show a blue bay, distant green hills, rooftops, and sailboat-like white specks on the water. Use a vivid cobalt-to-turquoise blue sky, towering sunlit clouds, strong afternoon light, and a sense that the journey has already begun. Render in a painterly Japanese anime illustration style with thick impasto-like brush texture, paper collage overlays, visible torn-paper geometric patches, halftone dot patterns, splattered paint accents, and bright watercolor/gouache colors. Add subtle decorative collage pieces in the corners and sky without covering the main scene. Place small elegant text in the bottom right reading {argument name="date text" default="May 26, 2026"} above a cursive artist signature {argument name="signature" default="Oyagi"}. No extra characters, no vehicles on the path, no modern UI, no border, no watermark beyond the small signature.
