In this captivating digital art piece, a cyberpunk mermaid with dark grey skin, glowing orange eyes, and sharp teeth, peers poignantly through a foggy glass window. The silver tail of the mermaid, subtly reflected on the glass, adds a mysterious allure to the composition. The scene sets in a gritty, cyberpunk city reminiscent of a John Singer Sargent environment, but infused with the modern digital techniques of artists like Maciej Kuciara, Craig Mullins, Yoji Shinkawa, and Ilya Kuvshinov. As black rain pours down, neon lights from the cityscape flicker, reflecting on the wet surfaces and enhancing the atmospheric tension of the scene. This hyper-realistic depiction not only showcases award-winning photography skills but also embodies the best style reference techniques in MidJourney, creating a hauntingly beautiful narrative that bridges the gap between the mythical and the mechanical.
