Create a seamless 15-second cinematic fantasy action sequence using @ Image 1, @ Image 2, and @ Image 3 as consecutive visual keyframes. Preserve the same moss-covered stone colossus, forest geography, riders, atmospheric lighting, ancient architecture, scale, and golden energy throughout.
0 to 5 seconds, @ Image 1: Begin instantly with an epic ultra-wide aerial view of the colossal forest valley. The camera rushes forward just above the glowing meadow as four riders gallop toward the advancing moss-covered colossus. Massive footsteps shake the ground, leaves swirl through the air, distant waterfalls flow, lightning flashes behind the trees, and clouds of mist rise around its legs. Maintain immense scale and realistic horse movement.
5 to 10 seconds, @ Image 2: Sweep rapidly between two gigantic tree trunks and transition into a dramatic low-angle tracking shot. Follow the riders and lone figure racing beneath the colossus as one enormous foot strikes the forest floor. Moss-covered stone fractures, roots split, boulders tumble, branches fall, and green dust erupts toward the camera. Introduce brief slow motion as debris, spores, leaves, and fragments float around the characters, then accelerate forward through the opening beneath the colossus.
10 to 15 seconds, @ Image 3: Snap back to full speed and surge upward along the colossus body. Break through clouds and waterfalls to reveal that its enormous head contains a hidden golden city. Orbit around the floating stone face as illuminated towers, bridges, temples, windows, and waterfalls emerge from the cracked skull. End with the camera diving through one glowing opening into the city while golden light fills the frame.
Use photorealistic cinematic detail, grand fantasy scale, smooth spatial continuity, dynamic parallax, volumetric forest light, realistic environmental destruction, natural motion blur, controlled camera shake, and detailed water simulation. Keep the colossus design consistent. No character duplication, sudden costume changes, deformed horses, unstable architecture, random scene changes, flickering details, text, logos, or desert imagery.
