Cosmic Jellyfish Subway Children

Create a vertical cinematic Korean webtoon-style fantasy illustration of two children standing ankle-deep in reflective water inside a dark abandoned underground station. The scene is dominated by one enormous translucent cosmic jellyfish floating overhead, its bell glowing with stars, nebulae, cyan, violet, and deep blue bioluminescence, with many long ribbon-like tendrils trailing down through the air. Below it, place exactly 2 children in the foreground: one dark-haired child on the left with a long braid, pale robe, a chest label reading “5”, and a small flashlight casting a warm beam into the water; one light-blond child on the right with short wavy hair, pale robe, a chest label reading “4.8”, holding a small plush bunny and raising one hand to present a glowing blue orb. The environment is a flooded, decaying subway concourse with escalators on the left, rows of pillars receding into a bright circular vanishing point, cracked walls, hanging droplets, glowing jellyfish-like bulbs scattered on the water surface, and illuminated poster panels showing abstract blue-purple light. Use dramatic perspective, glossy reflections, volumetric mist, tiny floating particles, high-detail anime linework, luminous painterly rendering, deep shadows, magical blue and purple rim lighting, and a melancholic dreamlike atmosphere. No extra characters, no modern signage beyond the two numeric chest labels, no watermark, no border.
