壮麗な都市を走るレトロフューチャーバイクの老いたクマのライダー

a striking, vintage illustration, retrofuturism, a kind of dirty sci-fi illustration, with a strong sense of sci-fi adventure. This style is a clear blend of European sci-fi and fantasy illustration, in the vein ofJean Moebius Giraud, of a weathered, elderly anthropomorphic Bear Black with a white beard and white hair, wearing large, round, reddish-brown goggles and a blue denim jacket over a cream-colored shirt, sits astride a futuristic yellow motorcycle. His trousers are a rusty reddish-brown, and he wears heavily textured, laced boots. Intricate metallic gloves cover its hands, gripping the handlebars. The motorcycle is a marvel of steampunk-inspired design, with a bulbous, rounded body and exposed mechanical details. In the background, a fantastical big city unfolds with tall, intricate buildings featuring domed roofs and ornate architecture, bathed in a bright, clear sky. The overall mood is one of adventurous exploration in a technologically advanced, retro-futuristic world. The perspective is a medium shot, slightly from below, emphasizing the imposing nature of the bear and his vehicle against the backdrop of the grand city. The overall mood is one of suspenseful and adventure, rendered in a detailed, painterly, science fiction art style. Highly detailed. The overall style suggests a blend of vintage sci-fi and thriller with influence of Moebius
