Prompt:
"Toxic Leviathan" is visible in the top center with ominous, flowing lettering that blends hyper-realistic textures with subtle cel-shaded outlines, giving a distinctly post-apocalyptic and terrifying aesthetic.
In the immediate foreground, a truly colossal humanoid-gastropod mutant emerges from a vast, swirling pool of toxic, iridescent green water. Its immense, realistically textured, slimy body, covered in pulsating, bioluminescent cel-shaded pustules, ripples as it moves. Its massive, realistically detailed head, outlined with menacing cel-shading, features grotesque eye stalks that extend upwards, and a gaping maw that drips with corrosive, hyper-realistic, cel-shaded fluid. Its single, powerful foot-like appendage, depicted with realistic suction cups and cel-shaded outlines, crushes the submerged, realistically textured, cel-shaded ruins of a city bus. The air is thick with noxious fumes, visibly swirling with subtle cel-shaded effects.
In the mid-ground, on a distant, corroded metal platform barely above the toxic water, two heroic figures are visible as small, desperate silhouettes against a faint, flickering red warning light. One, a female sharpshooter, is aiming a heavy rifle. Beside her, a male engineer, a larger silhouette, frantically works on a control panel. Their figures are tiny against the overwhelming scale of the creature.
The environment is a vast, desolate industrial complex, partially submerged in the glowing toxic waste, with realistically textured, rusted metal structures and cel-shaded, skeletal smokestacks piercing the oppressive, fog-filled atmosphere. The small text "digo.a.i" is subtly integrated as a sharply defined, glowing decal on the side of the submerged bus, appearing with a slight realistic texture. The artwork is a unique blend of hyper-realism for the monstrous threat and environmental texture, combined with bold cel-shaded outlines and a terrifying, stylized color palette to emphasize the immense, lurking danger in this hybrid-style post-apocalyptic nightmare.
