In a medium shot from a side angle, a graceful jellyfish personification relaxes in the shimmering depths of the deep sea. The character is a slender female with translucent, glowing pale-blue skin and long, flowing iridescent tentacles that drift like fabric around her body. She wears a sheer, diaphanous dress made of bioluminescent membranes that ripple like water, and she has soft, translucent fins extending from her head like delicate veils. She is floating serenely, holding a small, glowing piece of deep-sea plankton near her lips as if savoring a light meal, with a peaceful, half-closed gaze and a faint smile. The environment is a dark, atmospheric abyss filled with floating bioluminescent particles, drifting marine snow, and distant, glowing coral reefs that cast a soft neon light. The lighting is ethereal and moody, dominated by deep indigo and electric cyan hues, creating a tranquil and otherworldly atmosphere with a soft depth-of-field effect.
