Prompt

Stage 1: The historical figures of Meriwether Lewis, William Clark, and Sacagawea vividly step forward, creating a dramatic 3D parallax effect against the engraved background. Stage 2: The river at their feet flows with a choppy, animated current. Stage 3: The wind whips at their cloaks in a grand, adventurous flutter. Crucial Instruction: Maintain the monochromatic, violet-brown intaglio engraving style perfectly. Let the engraved lines themselves ripple to create the motion. Do not switch to a different scene or add objects not present in the original 1954 engraving.
