"Create a dramatic desert landscape at sunset, with silhouette figures traveling across the dunes. The sky should be ablaze with reds, oranges, and purples as the sun sets. The figures, in silhouette, could be a caravan of travelers with camels or a lone wanderer with a staff. Include elements like the long shadows cast by the dunes, distant palm trees at an oasis, and the shimmering heat waves rising from the sand. The scene should convey a sense of journey and endurance."
