Ilustración de Bellas Artes de Sirena con Cabeza de Pez

A tall vertical dark-fantasy fine art illustration of a lone [fish-headed mermaid] suspended upright in deep water, centered on the canvas. The creature has a pale corpse-white humanoid upper torso with gaunt anatomy, long thin arms with one hand pressed across the chest and the other hanging downward, stringy wet hair-like tendrils, and a large realistic fish head with one prominent round eye and a slightly open mouth. Its lower body is a long serpentine mermaid tail covered in countless overlapping metallic silver scales, tapering into a split fin near the bottom. The background is a textured abyssal navy-black underwater void, illuminated by faint shafts of cold light descending from the top center. Feature two vertical decorative zones: a narrow column of cracked white net-like geometric texture along the left edge, and a loose aura of irregular [gold] leaf cracks and dripping lines surrounding the creature on both sides. Mixed-media oil painting style with heavy impasto texture, scratched surfaces, tarnished metallic highlights, dramatic chiaroscuro, a muted blue-black palette, eerie sacred-icon composition, and intricately detailed scales and skin. No text, no border, no watermark.
