Ghibli-style Forest Tunnel Cyclist Wallpaper AI Image Prompt

A cyclist seen from behind, wearing a white short-sleeved shirt, dark shorts, and a helmet, rides a bicycle on a road enclosed by a natural tunnel formed by giant trees. The tunnel is made of countless branches converging toward the center, with a deep dark green forest in the foreground, the interior brightly lit by yellow-green sunlight, and layered green mountains and forests in the distance. The cyclist faces away from the camera, riding forward in a relaxed posture, the bicycle moving at a steady pace, full of dynamic forward motion. Vertical full-screen wallpaper, low-angle upward shot, the tunnel's branches create strong perspective leading lines, drawing the eye to the cyclist at the center, forming a natural framing composition. Strong backlighting, sunlight penetrating from deep within the tunnel, creating a bright yellow-green glow, the foreground in deep shadow, with strong contrast between light and dark, evoking a mysterious yet healing atmosphere. The color palette is dominated by deep ink green and emerald green, with bright lemon yellow and grass green inside the tunnel, and fresh blue-green in the distance, contrasting strongly yet harmoniously, a fairy-tale-like Japanese color scheme. At the end of the tunnel are rolling green mountains and dense forests, sunlight filtering through leaves casting dappled shadows, the background softly blurred to highlight the tunnel and the cyclist.
