<lora:Fantastic:1> digital painting immerses the viewer in an otherworldly underwater cavern. At its center is a mermaid with iridescent scales that shimmer in shades of teal and gold, her flowing hair merging with the bioluminescent currents. She holds a glowing orb, illuminating ancient carvings on the cavern walls. Schools of glowing fish swirl around her, their light reflecting off the jagged coral and creating a dreamlike, tranquil atmosphere.
