"positivePrompt": "A vast reflective salt flat at sunrise, centered on the same masked traveler and pack animal from the reference image. The camera begins low and wide, gliding beside them as their footprints press into the thin crust and faint dust curls around their steps. Heat shimmer ripples across the horizon. In the distance, irregular crystal spires catch warm light and throw fractured reflections across the ground. The traveler’s layered robes flutter in gusts, metal charms gently clink, and the animal’s cargo sways with believable weight. Mid shot as the pair crest a subtle ridge of salt, revealing an enormous mirage-like reflection of the sky on the surface, with tiny whirlwinds tracing elegant arcs. Finish with a slow rising shot that reveals the caravan moving through an immense luminous landscape, serene, surreal, premium cinematic realism, finely detailed textures, atmospheric depth, physically plausible motion, dramatic scale, natural color grading, immersive environmental sound.",

Nearby hedges ripple in a light breeze, hanging paper charms flutter, distant pavilion lights shimmer, and a flock of white cranes lifts across the sky. The camera performs a slow dolly with gentle parallax, preserving the subject's identity and costume details from the input image. Luxurious advertising-grade realism, refined textures, delicate atmospheric depth, polished cinematic lighting, natural motion, stable composition, immersive ambient soundscape with soft footsteps on stone, porcelain clinks, faint steam hiss, evening insects, and distant birds.",

"positivePrompt": "A towering agricultural guardian mech stands in a vast late-summer wheatfield at golden hour, designed with brushed brass panels, ceramic joints, faded safety markings, and soft orange indicator lights. Small birds circle around its shoulders as the machine slowly wakes and rises from a kneeling position. The camera begins low among the wheat heads, gliding forward through the stalks, then arcs upward into a dramatic medium-wide reveal as the mech takes a careful step, scattering chaff and bending the grain in rippling waves. In the distance, low hills, irrigation canals, and a cluster of white silos catch the warm sunlight. Dust motes drift through the air, cloth pennants flap from thin poles, and the mech’s hydraulic limbs move with believable weight and restraint. Cinematic realism, rich texture, crisp fine detail, atmospheric depth, subtle lens bloom, natural color grading, premium advertising-style composition, immersive environmental sound with creaking metal, servos, rustling wheat, wings overhead, and a faraway tractor engine.",
