Prompt: Create a vertical, high-quality photograph-like image, featuring a woman with natural and casual attire in the foreground, slightly looking to the side. Her clothing should be colorful. She should be realistically rendered and of average height, possibly interacting with an object. The background is an intricately structured, richly colored underground space with a nostalgic atmosphere, including complex stairs leading further underground. The ceiling and floor resemble a natural cave, and the walls have a stone-like color. The environment includes dense plant life and various colorful objects, creating a slightly darker but warm and inviting environment with soft, nostalgic lighting.
