A haunting image of a sinister merman emerges, with a demented grin twisting his features, piercing yellow eyes glowing in stark contrast to his pallid skin. His elongated arms and sharp, webbed fingers hint at a predatory nature, while his fish-like tail boasts scales shimmering with an eerie sheen. The dynamic lighting casts dramatic shadows across his muscular torso, highlighting sinewy details. In the dark background, faint outlines of underwater ruins contribute to a melancholy atmosphere, as bubbles rise lazily around him, enhancing the cinematic quality of the scene.
