Whistling Dragon in a Cartoon Steam Engine

A cheerful cartoon dragon with bright emerald green scales, big round yellow eyes, and a friendly smile perched inside the cab of a vintage steam locomotive. The dragon is curiously tugging a red lever with one claw while steam billows from the boiler and the whistle. The locomotive is a classic black steam engine with brass fittings, riveted plates, a tall smokestack, a bell, and exposed gears. Inside the cab, gauges, pipes, and a small conductor hat sit beside the dragon, giving a playful, adventurous vibe. Warm sunset light bathes the scene, with a soft countryside landscape and fluffy clouds in the distance. Bold cartoon outlines, flat vibrant colors, simple shading, and exaggerated proportions typical of children's illustration. The perspective is a three-quarter view from outside the locomotive, focusing on the dragon and the control area for a whimsical, family-friendly image.
