Painted Railway Dream

Create a three-dimensional impasto oil-painting illustration as a native exact 4:5 vertical gallery-card composition, like a carved relief mural made from thick flowing paint. Build a whimsical storybook world with a starry sky, warm sun, soft clouds, a large creamy off-white color field, an open wilderness, rolling hills, a Tibetan palace on a hill, and a flower-covered railway leading through the scene. Place a small steam train on the railway, surrounded by colorful flowers along both sides of the track, with extremely fine flower details, clear carved paint ridges, visible brush strokes, raised pigment texture and sculptural linework. Use colorful light, Tyndall rays, luminous atmosphere, rich but organized detail, joyful childlike wonder and ultra-clear high-resolution finish. Keep the palace, train, railway, flower fields, sun, clouds and strongest carved details comfortably inside the central safe area. Avoid flat digital poster look, muddy paint, overcrowded chaos, unreadable text, watermark, copied signature, cropped train, cropped palace, cropped sun or low-resolution blur.
