Deep-sea glowing creature with tentacles

A solitary deep-sea creature drifts in a pitch-black abyss with bioluminescent tentacles unfurling like living ribbons, conveying quiet intent and distant intelligence. The scene reads as a study of form and atmosphere with no lettering on any surface and micro markings reduced to abstract lines. The water is clear but dense with pressure, and a faint particulate haze gives depth to the void. The creature's skin alternates between smooth, wet membranous folds and a subtly ridged mantle for tactile contrast. Focus falls sharply on the nearest tentacle tips and the creature's luminous mantle while the rest recedes into softened recession for moderate depth. Light sculpts the anatomy with a soft glow that gently separates forms and emphasizes iridescent cyan and teal accents against deep navy and amethyst shadows. Frame the composition within a 16:9 cinematic crop, tight to medium framing, eye-level viewpoint with balanced negative space to the right for implied motion. Include one small drifting jelly-like orb and a shard of bioluminescent plankton to cue ecosystem context. Render as a photoreal digital painting with subtle painterly grain to suggest organic texture. Tentacle motion conveys slow undulation and elegant drift rather than abrupt action.
