Ethereal elf woman on a floating island above nebula

An ethereal elf maiden with silver hair and eyes like twilight stars, standing on a floating island above a nebula of cosmic dust. She holds a staff that pulses with soft, internal light. The background is a swirling galaxy of impossible colors. This piece is in the style of digital painting with surrealist influences, akin to the concept art of artists like Michael Whelan and H.R. Giger, focusing on dreamlike, otherworldly beauty.
