Ethereal Unicorn Enchantress at Dusk

A poised female figure with a spiraling crystalline horn commands the foreground, her cascading hair shifting from deep violet to icy blue and catching scattered starlight. Intricate silver armor, chased with filigree and set with faceted gems, contours her form while a high collar frames the elegant line of her neck. She turns slightly, gaze steady, against a horizon where sunset oranges dissolve into indigo twilight over calm water. Warm light from the low sun gilds the edges of her armor and hair, while cool magical highlights and floating particles create a luminous counterpoint. The palette moves between molten gold, lavender, and midnight blue, producing a mood of serene majesty and otherworldly grace. The rendering recalls classical fantasy illustration with contemporary digital precision, emphasizing texture in metal, hair, and rippling reflections.
