Use the attached reference image as the strict identity and design reference. Preserve exactly the same 11-year-old boy: short black hair, oversized brown eyes, mustard-yellow sweater, dark green trousers, worn brown boots, bright red jacket tied around his waist. Preserve exactly the same stocky middle-aged train driver: square face, thick black moustache, navy railway cap and navy uniform. Preserve exactly the same old dark-green diesel locomotive with cream stripe, round headlights and weathered metal. Visual style must be deliberately uncanny broken low-poly 3D, early-2000s video-game cutscene, angular asymmetrical anatomy, stiff puppet-like forms, crude geometry, gritty semi-realistic textures, muted cold blue-grey and muddy-brown palette, dramatic overcast light, surreal scale, no text, no captions, no logos. Vertical 9:16. KEYFRAME C — THE WARNING. Dynamic side view at track level. The same boy has removed the bright red jacket from his waist and runs directly toward the oncoming same locomotive along the safe intact rails, waving the red jacket high with both hands. His body is angular and puppet-like, face frightened but determined. The train is huge behind him, headlights glowing through fog. Motion-ready composition, full boy visible, no collision.
