Blue Floral Fantasy Portrait

Create a vertical cinematic fantasy portrait of a young woman sitting in a dreamy blue-and-white flowering garden, wearing an elegant flowing {argument name="dress color" default="white-to-aqua blue"} gown with translucent layered fabric, dark ink-like floral branch patterns across the bodice and one sleeve, and a wide billowing skirt spread around her. She has very long wavy {argument name="hair color" default="black"} hair and an ornate oversized floral headpiece made of exactly 4 prominent flower clusters: one bright cyan flower on the upper right, one pale pink blossom behind it, one white flower cluster near the ear, and one vivid blue flower on the left side, surrounded by fine twig-like sprays and small leaves. Pose her seated in three-quarter view, torso turned slightly left, one hand resting gently near her chin and the other hand relaxed on her lap. Place her among blooming branches with exactly 2 dominant blossom colors, electric cyan-blue and soft white, with leaves and petals framing the foreground. Use a shallow depth of field with large blurred blossoms in the lower left foreground, a bright high-key white sky background, cool blue color grading, soft backlight, ethereal bokeh, and ultra-detailed fabric texture. The face should appear softly blurred and indistinct, while the hair, flowers, hands, and dress remain sharply rendered. Style: photorealistic fantasy fashion photography, delicate, romantic, luminous, 9:16 vertical composition, no text, no watermark.
