"Create a 3D model of a natural stone archway with rugged, uneven rock formations and a staircase leading to the arch. Highlight jagged textures, weathered stone surfaces, and realistic cracks. Ensure lifelike proportions, intricate details on the arch and surrounding rocks, and smooth integration of the stairs with the ground. Use balanced, natural lighting to emphasize texture depth and maintain ultra-realistic detail in all elements of the model."
