Prompt

Animate the massive gray stone carving by making the three horses gently toss their heads and swish their tails within the rock wall. Have the riders shift slightly in their saddles and pull back gently on the reins. Animate fine dust particles, rendered in the exact gray engraved texture, drifting down the mountain face. Pulse the sky with a slow, dramatic light change. CRITICAL INSTRUCTIONS: Preserve the original gray monochromatic engraved aesthetic of the stamp. Only animate the items already found on the stamp. Do not add new items or switch scenes.
