A Train Through Four Seasons

Generate exactly one original richly painted anime illustration, landscape 16:9, text only with no reference pixels. Look straight down a long railway carriage through four aligned open connecting doorways. Each successive compartment contains a different season: sunny summer in front, swirling autumn leaves next, soft winter snow farther back, and blossoming spring at the end. An adult conductor pushes one luggage trolley across the nearest seasonal threshold; its front wheel crushes a dry leaf while its rear wheel stays in a summer puddle. A single gust carries leaves toward the snow, joining the spaces into one event. Warm wood, teal upholstery, precise diminishing perspective, expressive adult face. No signs, readable print, brands or watermark.
