A vibrant, close-up portrait of a tiefling woman with striking azure skin and ethereal, swirling patterns reminiscent of a cosmic tapestry. Her lush, spiraling horns curve gracefully above her head, their surface glittering with a subtle iridescence. Sharp, glowing eyes peer out from beneath elegantly arched brows, their gaze intense and enigmatic. Her features are a harmonious blend of demonic allure and mysterious charm, with delicate markings tracing the contours of her face. Her hair cascades like a waterfall of shadows interspersed with shimmering cosmic dust, adding an otherworldly aura. Inspired by the rich, painterly style of Arcane, the image combines elements of demon anime aesthetics with the intricate design of a dnd tiefling. Her expression is both fierce and contemplative, capturing the essence of a powerful and enigmatic demon girl from a mystical realm.
