Gently smiling cyber mermaid in a flowing, iridescent tailcoat, sitting on a weathered stone at the ocean's edge, under a starry night sky, with her tail glowing brightly in a vibrant teal neon fluorescent hue, reminiscent of a cyberpunk dream. The scene is set in a cinematic film still, with the look of a 35mm film shot on a v-raptor XL, showcasing film grain and a subtle vignette. Inspired by the dramatic, atmospheric styles of Simon Stalenhag, the cinematic lighting evokes a sense of wonder, while the neon colors recall the futuristic visions of Ash Thorp. With a post-processing aesthetic akin to a blockbuster film, the image is a live-action, atmospheric masterpiece, with the mermaid's presence radiating an epic, stunning drama, as if captured by the lens of a legendary cinematographer.
