The pixel art image depicts a single, eerie mermaid figure against a pure black background. The mermaid is positioned centrally within the frame, occupying most of the vertical space and a significant portion of the horizontal, drawing the viewer's immediate attention. She faces directly forward, her body angled slightly towards the left. Her expression is unsettling, with sunken eyes and gaunt features, suggesting a spectral or undead nature. Her mouth is closed but her facial structure implies a grimace or a state of decay, contrasting sharply with the typically beautiful depiction of mermaids. Her hair is depicted as voluminous and wildly flowing, a mass of dark teal strands with lighter highlights suggesting movement through water or an otherworldly energy. Her upper body is bare, revealing a skeletal ribcage and a very lean physique, which transitions into a beautifully detailed fish tail. The tail is broad and scales are clearly delineated through varying shades of teal and dark blue, creating a sense of texture and depth. Wavy, ethereal tendrils of what appears to be water or a ghostly aura emanate from her left side and beneath her tail, adding to the supernatural quality. The dominant colors in the palette are various shades of dark teal, ranging from a deep, almost black teal to a lighter, more vibrant aqua, interspersed with muted greens and blues for her skin and hair. The overall color scheme is cool and dark, with a striking contrast provided by the pure black background, which further emphasizes the mermaid's form. The vibe is decidedly ominous and mysterious, bordering on gothic horror, evoking a sense of ancient dread or a ghostly encounter rather than a whimsical fantasy. There are no additional UI elements or text, keeping the focus entirely on the spectral mermaid.
