Perched on a Translucent Jellyfish, Her Gown Glows Too

A young woman with fair skin and wavy brown hair styled into an elegant updo dotted with delicate beads sits gracefully atop a large, translucent jellyfish-like creature in an underwater setting, her expression serene and contemplative. One hand rests thoughtfully against her chin while the other lies on the jellyfish's translucent surface; her ankles are crossed, delicate ankle-high sandals matching the flowing, ethereal gown that echoes the jellyfish's own translucent, umbrella-like form — shimmering blue-and-white layers built from crystal-like sparkle and intricate lace. Around her, soft glowing light filters through a mystical underwater scene, with numerous jellyfish trailing flowing, translucent tentacles and ancient, arch-like structures hinting at a sunken palace in the background. Keep the overall palette in shades of blue, purple, and white, with sparkling highlights that give the whole image a magical, otherworldly feel.
