Treno Galattico nella Vecchia Aula

A cinematic vertical anime illustration of a quiet, old art classroom after rain. On the left, [a teenage schoolgirl] sits sideways on the edge of a worn wooden desk, featuring [long wavy dark brown hair], expressive eyes, a wistful expression, wearing [a cream cardigan over a teal blouse with a long navy skirt and brown shoes]. Late-afternoon golden sunlight streams through three large windows on the right, where sheer white curtains drift softly, revealing a wet courtyard, greenery, and reflected buildings in puddles outside. The rustic classroom contains a chalkboard with faint notes and pinned sketches on the back wall, two wooden desks, an open sketchbook with architectural drawings, brush jars, stacked books, framed paintings, a plaster bust, stools, and weathered floorboards. A magical transformation unfolds as the girl's shadow stretches across the floor and becomes [a luminous miniature galaxy train]: a glowing silver-white train curving along cosmic starry rails, accompanied by tiny planets, nebula dust, constellations, and floating paper fragments. Detailed Japanese anime painterly style, volumetric sunbeams, warm amber room tones contrasted with deep cosmic navy blues. High detail, vertical composition, no extra characters, no watermarks.
