深海里獨自發光的那隻水母

A single bioluminescent jellyfish hangs upright in a deep vertical expanse, framed 9:16 tall to play up vertical motion and the graceful drift of its tentacle trails. Its translucent bell throws soft teal and violet light into the surrounding dark water, aiming for an immersive, serene feel. Surfaces stay clean and unlettered; the jellyfish's skin reads glossy and faintly iridescent, its delicate filaments catching the light like thin glass and silk. The deep-sea setting holds a cool, clear atmosphere with a gentle particulate haze picking up the glow. Focus resolves sharpest on the bell and the nearest tentacle edge, with moderate layering softening into deeper background planes. Light sculpts the forms with gentle separation and a subtle rim glow, landing an overall cool color bias balanced by pale green highlights. The tight, tall composition sits at eye level with narrow negative space above and below to stretch the sense of rise, the jellyfish placed slightly off-center for quiet tension. Small drifting plankton and a faint, distant coral silhouette anchor scale and story. Rendered as a photorealistic digital painting, the water finely textured with luminous scattering that captures the jellyfish's calm kinetic drift.
