Underground City Princess: Hyper-Real 3D Render

Ultra-detailed photorealistic 3D render of a regal princess standing in an expansive subterranean city. She wears a flowing iridescent gown and a delicate jeweled circlet, with a cloak trailing behind her. The underground metropolis is carved from stone and crystal, illuminated by bioluminescent fungi, glowing canals, and hanging lanterns. Grand arches, vaulted ceilings, stalactites, and brass bridges weave through the cityscape. Cinematic lighting with warm amber highlights and cool blue-green shadows, rim light along her silhouette. Market stalls, rune-inscribed signs, and distant figures moving through reflective water. Wide, slightly low-angle shot to emphasize scale; deep depth of field with the princess in sharp focus and the background softly blurred. Style: hyper-realistic 3D render with detailed textures: polished obsidian, brass, glass, fabric, and moss.
