A majestic photorealistic portrait of Selene, ancient Greek goddess of the moon, standing on a high marble terrace above a sleeping Mediterranean landscape. Vertical half-length composition, Selene positioned slightly left of center and looking directly into the camera with a serene, mysterious and timeless expression. Regal adult woman with a symmetrical oval face, luminous porcelain skin, delicate freckles, high cheekbones, silver-blue almond-shaped eyes, long dark eyelashes, refined straight nose and naturally shaped pale rose lips.
Her extremely long platinum-blonde hair falls in thick, voluminous curls and luminous ringlets, gently floating as if touched by celestial energy. She wears a flowing midnight-blue and silver Grecian gown embroidered with stars, crescent moons and fine antique-silver filigree. A broad iridescent scale collar reflects pearl white, turquoise, violet and moonlight blue. A delicate silver crescent diadem rests above her forehead.
A magnificent white horse stands behind her on the viewer’s right, its mane illuminated by moonlight. Selene holds an ornate silver staff crowned by a glowing crescent moon.
A gigantic full moon dominates the sky behind her, surrounded by stars, dramatic clouds and silver volumetric rays. Ancient Greek columns, distant mountains and a moonlit sea remain sharply visible. Blue magical particles and stardust surround her hair and gown.
