Fantasy girl with pastel hair in ethereal underwater light

Fantasy portrait of a young woman with flowing pastel lavender-pink hair that drifts around her. She wears a delicate crown of tiny white flowers and pearls; her skin is luminous and pale, with large expressive eyes and soft pink lips. She dons a shimmering translucent sea-silk top that clings to her shoulders. The scene is bathed in gentle, ethereal light with sunbeams filtering from above, caustic light patterns on her skin and pastel coral in the background. Color palette: cool blues and aquas with pinks and purples. Mood: dreamy, magical. Style: hyper-detailed digital painting with painterly brushwork or high-fidelity fantasy realism. Texture details: wet hair strands, delicate reflections. Composition: close-up, head-and-shoulders, three-quarter view, shallow depth of field.
