portrait poster design — Oversized title, stacked type with multi-line title

A horror movie poster in a painted-illustration style shows a green gilled humanoid creature rising through deep water, set against a dark teal underwater scene. Murky teal water fills the frame, darker toward the edges and glowing pale green near the surface above. At the center of the composition, the creature's bulky scaled body looms toward the viewer, its broad head and shoulders dominating the middle of the frame. Its face is a mask of ridged green skin with flared gill slits on the cheeks, heavy-lidded dark eyes, and a wide downturned mouth. On the left side of the frame, its massive right arm rises overhead, the clawed hand spread wide with long ivory-white talons. Dark fringed fins edge its forearm and shoulder like tattered membranes. Its left arm hangs lower on the right side of its body, half-hidden among drifting weeds. The creature's torso is armored in overlapping green scales that catch the light across the chest and shoulders. Above the creature, near the water's surface, a bright glow filters down in pale shafts. In the upper-right corner, a dark silhouette of a swimmer glides across the surface light, trailing bubbles. To the right of the creature, a second smaller diver descends headfirst through the water, a stream of silver bubbles rising from the mask. Below the second diver, a third figure in diving gear sinks deeper with arms slightly outstretched. On the left edge of the frame, black silhouettes of tall kelp fronds sway in the current. Across the lower middle band, dense black water-plants form a shadowy thicket around the creature's legs. In the lower-right corner, more dark fronds rise against the deep blue water. Across the bottom third, the poster "TITLE" appears in huge arched orange block letters with a teal-green drop shadow, stacked in three lines. The letters lean with a hand-drawn pulp energy, the middle line smaller and tucked between the larger lines above and below it. The lighting is aqueous and directional, with cold sunlight piercing from the surface above and raking across the creature's scales. Highlights glint on the white claws and the wet dome of the creature's head, while the lower depths dissolve into inky black-green shadow and small drifting particles hang suspended in the water. Overall, the poster balances a looming central monster against a luminous aquatic backdrop, its palette of deep teal, moss green, and hot orange delivering a lurid, vintage monster-movie thrill.
